Meditation: What is the significance of Jesus spending 40 days and nights of solitude, prayer and fasting in the Judean wilderness? In the Old Testament 40 days was often seen as a significant period of testing and preparation for entering into a covenant relationship with God. In the days of Noah, God judged the earth and destroyed its inhabitants in a great flood because of their idolatry and total rejection of God. Noah and his family were spared because they obeyed God and took refuge in the ark for 40 days. When the flood subsided God made a covenant with Noah and promised that he would not destroy the human race again. Jesus came to fulfill that promise.
Forty days of retreat to seek the face of God
When God freed the Israelites from slavery in Egypt he brought them into the wilderness of Sinai. Moses went to the mountain of the Lord at Sinai and remained there in prayer and fasting for 40 days (Exodus 24:18). At the conclusion of this 40 day encounter God made a covenant with Moses and the people. After the prophet Elijah had confronted the sin of idolatry (the worship of false gods) in the land of Israel and destroyed the 400 priests of Baal (1 Kings 18:20-40), he fled into the wilderness and journeyed for 40 days to the mountain of God at Sinai (1 Kings 19:8). There God spoke with Elijah and commissioned him to pass on the work of restoring the worship of the one true God in the land. After Jesus was anointed by the Spirit in the waters of the Jordan River, he journeyed to the wilderness of Judea for 40 days to prepare himself for the mission which the Father sent him to accomplish – to offer up his life as the perfect atoning sacrifice for our sins. Through the shedding of his blood on the cross he won for us a new and everlasting covenant which fulfilled and surpassed all the previous covenants which God had made with his people.
God’s Word and Spirit sustains those who seek God’s will
Matthew, Mark, and Luke tell us in their Gospel accounts that Jesus was led by the Holy Spirit into the wilderness. Mark states it most emphatically: “The Spirit immediately drove him out into the wilderness” (Mark 1:12). Why was Jesus compelled to seek solitude for such a lengthy period? Was it simply a test to prepare him for his ministry? Or did Satan want to lure him into a trap? The word tempt in English usually means to entice to sin or wrong-doing. The scriptural word here also means test in the sense of proving and purifying someone to see if there are ready for the task at hand. We test pilots to see that they are fit to fly. Likewise God tests his servants to see if they are fit to be used by him.
God tested Abraham to prove his faith. The Israelites were sorely tested in Egypt before God delivered them from their enemies. Jesus was no exception to this testing. Satan, in turn, did his best to entice Jesus to chose his own will over the will of his Father in heaven. Despite his weakened condition, due to fatigue and lack of food for 40 days, Jesus steadfastly rejected Satan’s subtle and not so subtle temptations. Where did Jesus find his strength to survive the desert’s harsh conditions and the tempter’s seduction? He fed on his Father’s word and found strength in doing his will. Satan will surely tempt us and will try his best to get us to choose our will over God’s will. If he can’t make us renounce our faith or sin mortally, he will then try to get us to make choices that will lead us, little by little, away from what God wants for us.
As soon as John the Baptist had finished his ministry, Jesus began his in Galilee, his home district. John’s enemies had sought to silence him, but the Gospel cannot be silenced. Jesus proclaimed that the time of restoration proclaimed by the prophets was now being fulfilled in his very person and that the kingdom of God was at hand. What is the kingdom of God? The word “kingdom” means something more than a territory or an area of land. It literally means “sovereignty” or “reign” and the power to “rule” and exercise authority. The prophets announced that God would establish a kingdom not just for one nation or people but for the whole world. God sent us his Son, the Lord Jesus Christ, not to establish an earthly kingdom but to bring us into his heavenly kingdom – a kingdom ruled by justice, truth, peace, and holiness. The kingdom of God is the central theme of Jesus’ mission. It’s the core of his Gospel message.
Two conditions for the kingdom – repent and believe
How do we enter the kingdom of God? In announcing the good news of the Gospel Jesus gave two explicit things each of us must do in order to receive the kingdom of God: repent and believe. Repent means to turn away from sin and wrong-doing in order to follow God’s way of love, truth, and moral goodness. When we submit to God’s rule in our lives and believe in the Gospel message the Lord Jesus gives us the grace and power to live a new way of life as citizens of his kingdom. He gives us grace to renounce the kingdom of darkness ruled by pride, sin, and Satan, the father of lies (John 8:44) and the ruler of this present world (John 12:31). Repentance is the first step to surrendering my will and my life to God.
Repentance means to change – to change my way of thinking, my attitude, my disposition, and the way I choose to live my life – so that the Lord Jesus can be the Master and Ruler of my heart, mind, and will. Whatever stands in the way of God’s will and plan for my life must be surrendered to him – my sinful pride, my rebellious attitude, and stubborn will to do as I please rather than as God pleases. If I am only sorry for the consequences of my own sinful ways, I will very likely keep repeating the same sins that control my thoughts and actions. True repentance requires a contrite heart and true sorrow for sin (Psalm 51:17) and a firm resolution to avoid the near occasion of sin. The Lord Jesus gives us the grace to see sin for what it really is – a rejection of his love, truth, and wisdom for our lives and a refusal to do what he says is right and good for us. His grace brings pardon and freedom from guilt, and breaks the power of bondage to sin in our lives through the strength and help of the Holy Spirit who dwells within us. If we yield to the Holy Spirit and not to our sinful inclinations, we will find the strength and help we need to turn away from all wrong-doing and whatever else might keep us from living in his truth and love.
To believe is to take Jesus at his word and to recognize that God loved us so much that he sent his only begotten Son to free us from bondage to sin and harmful desires. God made the supreme sacrifice of his Son on the cross to bring us back to a relationship of peace, friendship, and unity with our Father in heaven. He is our Father and he wants us to live in joy and freedom as his beloved sons and daughters. God loved us first and he invites us in love to surrender our lives to him. Do you believe in the Gospel – the good news of Jesus Christ – and in the power of the Holy Spirit who transforms each one of us into the likeness of Christ?
Lord Jesus, your word is life, joy, wisdom, and strength for me. Fill me with your Holy Spirit that I may have the strength and courage to embrace your will in all things and to renounce whatever is contrary to your will for me.
Psalm 25:4-9
4 Make me to know your ways, O LORD; teach me your paths.
5 Lead me in your truth, and teach me, for you are the God of my salvation; for you I wait all the day long.
6 Be mindful of your mercy, O LORD, and of your steadfast love, for they have been from of old.
7 Remember not the sins of my youth, or my transgressions; according to your steadfast love remember me, for your goodness’ sake, O LORD!
8 Good and upright is the LORD; therefore he instructs sinners in the way.
9 He leads the humble in what is right, and teaches the humble his way.
Daily Quote from the Early Church Fathers: The call to repentance, by Chromatius (died 406 AD)
“The voice of the Lord urging the people to repentance – the Holy Spirit made it known to the people that they might take heed, saying, ‘Today, when you hear his voice, do not harden your hearts as in the rebellion, as in the day of testing in the wilderness’ (Psalm 95:8). In the same psalm above, he made clear that he was urging the sinful people to repentance and showed the state of a repentant soul, saying, ‘Come, let us fall down before him and lament before the Lord who made us, for he is our God’ (Psalm 95:6-7). The Lord urges the people to repentance, and he promises to pardon their sins, according to Isaiah’s words: ‘I, even I, am the one who wipes out your iniquities, and I will not be mindful of your sins. But you be mindful, declare first your iniquities that you may be justified’ (Isaiah 43:25-26). Rightly then does the Lord urge the people to repentance when he says, ‘Repent, for the kingdom of heaven is at hand,’ so that through this confession of sins they may be made worthy to approach the kingdom of heaven.” (excerpt from TRACTATE ON MATTHEW 15.3)
[Note: Chromatius was an early Christian scholar and bishop of Aquileia, Italy. He was a close friend of John Chrysostom and Jerome. He died in 406 AD. Jerome described him as a “most learned and most holy man.”]
