1 Corinthians 10:3-4

3 They all ate the same spiritual food 4 and drank the same spiritual drink; for they drank from the spiritual rock that accompanied them, and that rock was Christ.

When the Israelites were released from the bondange of salavery in Egypt, they did not enter directly into the land promised by God. Rather, they wandered 40 years in the wilderness before settling in the promised land. During this long journey, they arrived at Rephidim where they could not find any water and became thirsty. They quarreled with Moses and compalined their being led to the desert and died there. By this event, we can see that the Israelites had forgotten the power and grace of God who saved them from the bondage of slavery in Egypt and their continuous protection, guidance and provision in the desert. Their lack of faith and gratitude were revealed in a simple test of thirst. Instead of praying to God for provision, they turned to be a dissatisfying crowd of people and were ready to stone Moses to dead. Again, by God's grace, they were not punished by this offense. Instead, God answered Moses' call and performed a miracle in Horeb to quench their thirst. Moses was asked to strike a rock at a place called Horeb and water would come out of the rock (Exodus 17:6). This miracle is an image of Christ being striken (Isaiah 53:4) such that all sinners who come to Christ may receive the living water such that a sinful, and dissatisfying life can be transformed into a new and abundant life in Christ by the work of the Holy Spirt (John 7:37-39). How gracious is our God who does not remember our sins and paid for the wages of sins by His Son and blesses us with a new life born with the Holy Spirit when we come to Jesus Christ.

Exodus 17:6

6 I will stand there before you by the rock at Horeb. Strike the rock, and water will come out of it for the people to drink." So Moses did this in the sight of the elders of Israel.

Isaiah 53:4

Surely he took up our infirmities and carried our sorrows, yet we considered him stricken by God, smitten by him, and afflicted.

John 7:37-39

37 On the last and greatest day of the Feast, Jesus stood and said in a loud voice, "If anyone is thirsty, let him come to me and drink. 38 Whoever believes in me, as the Scripture has said, streams of living water will flow from within him." 39 By this he meant the Spirit, whom those who believed in him were later to receive. Up to that time the Spirit had not been given, since Jesus had not yet been glorified.

An evidence that we have faith in Jesus is that we have the living water that is the Holy Spirit that Jesus promised. If the Holy Spirit lives in our life, we will be reminded of the teachings of Jesus as recorded in the scriptures John 14:26. When we put His teachings into practice we are like building a house on the solid rock. Difficulties, challenges and temptations in life bound to come to all people including believers of Christ. But, Jesus promises that it will not result in a disastrous collapse as houses built on other temporary and unreliable foundation (Matthew 7:24-27). Indeed Christ is the one we can trust. His words are effective and true that we can depend on until eternity.

John 14:26

But the Counselor, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.

Matthew 7:24-27

24 "Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock. 25The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock. 26But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. 27The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash."
