Exodus, Chapter 9, Verse 27-30
27 Then Pharaoh sent for Moses and Aaron and said to them, “I have sinned this time! The LORD is the just one, and I and my people are the ones at fault. 28 Pray to the LORD! Enough of the thunder and hail! I will let you go; you need stay no longer.” 29 Moses replied to him, “As soon as I leave the city I will extend my hands to the LORD; the thunder will cease, and there will be no more hail so that you may know that the earth belongs to the LORD. 30 But as for you and your servants, I know that you do not yet fear the LORD God.”
This was the seven plague of God on the Egyptians and of course Pharaoh had closed his ears and heart to God. Thunder was to the Egyptians the voice of God but they did not listen nor did the hail melt the ice of their hearts to the true God.
Because God loves us He sometimes permits plagues in our lives that will bring about an exodus from our sin and a melting of our heart. When we are poor in spirit it is then that we can draw near to the Lord. A young man approached Jesus and said, “Teacher, what good must I do to gain eternal life?” He answered him, “Why do you ask me about the good? There is only One who is good. If you wish to enter into life, keep the commandments.” He asked him, “Which ones?” And Jesus replied, “You shall not kill; you shall not commit adultery; you shall not steal; you shall not bear false witness; honor your father and your mother; and you shall love your neighbor as yourself.” The young man said to him, “All of these I have observed. What do I still lack?” Jesus said to him, “If you wish to be perfect, go, sell what you have and give to the poor, and you will have treasure in heaven. Then come, follow me.” When the young man heard this statement, he went away sad, for he had many possessions. (Mt. 19:16-22)
