Jesus fasted forty days and forty nights and was tempted by the devil

Gospel Reading: Mark 1:12-15
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. 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 stayed 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 idolaty in the land of Israel and destroyed the 400 priests of Baal, he fled into the wilderness and journeyed for 40 days to mountain of God at Sinai. There God spoke with Elijah and commissioned him to pass on the work of restoration of true worship of God in the land (1 Kings 19:8). After Jesus was annointed 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 in establishing a new covenant that would supercede all the previous covenants which God had made with his people.
