In Genesis 6, God told Noah that He would destroy the earth by flood.  There was such great violence in the earth that God was grieved, and He regretted that He had created humankind.  Genesis 6:5-8.  God provided a way of escape for Noah, his family and for anyone who chose to believe in His coming judgment.  Sad to say, only Noah, his wife, his sons and their wives were saved. After the flood, God made a covenant with mankind never to destroy the earth by flood again.  Genesis 9:8-17.  

The rainbow is a sign of God's covenant.  God has been faithful to keep His covenantal promise.  In Exodus 34:6-7, God described Himself to Moses, "And He passed in front of Moses, proclaiming, The LORD! the LORD! the compassionate and gracious God, slow to anger, abounding in love and faithfulness, maintaining love to thousands, and forgiving wickedness, rebellion and sin......" (NIV). God is faithful.  2 Timothy 2:13 says, "If we are faithless, he remains faithful, for he cannot disown himself."  Faithful means to remain loyal and steadfast.  It also means to keep your promise or to do what you are supposed to do.  God does not change.  He is the same yesterday, today and forever.

In Genesis 3, God promised that the offspring of the woman would crush satan's head and defeat him.  Genesis 3:15 says, "And I will put enmity between you and the woman, and between your offspring and hers; he will crush your head and you will strike his heel."  Two thousand years ago Jesus crushed satan's head at the cross.  At Jesus' last Passover, He instituted the new covenant.  Matthew 26:26-28. Jesus chose to lay down His life for us on the cross and redeem us with His precious blood.  God raised Jesus from the dead and now He is seated in heaven at the right hand of the Father.  Jesus overcame sin, death and the devil and crushed satan's head and defeated him, just as God promised.  Colossians 2:9-15 tells us Jesus triumphed over every principality and power at the cross.

God promises that no harm shall come to us as we serve Him and fulfill the Great Commission.  He promises to be with us always.  Matthew 28:18-20. He promises us that as He was with Moses, so will He be with us.  Joshua 1:1-5. No one can snatch us out of His hands.  He will keep us from all harm.  Psalm 16:5-8, John 10:27-30.

Jesus told us that the end times will be just as the days of Noah.  There is great violence in the earth.  There are many wars in many places and many people are distracted by the pleasures of the world and are not paying attention to the signs of the times.  However, just as how God provided the ark to protect Noah and his family, God has provided the ark of Jesus Christ to protect us and anyone who choose to receive Jesus as their Lord and Savior.

Revelation 3:10-13 says, "Since you have kept my command to endure patiently, I will also keep you from the hour of trial that is going to come on the whole world to test the inhabitants of the earth.  I am coming soon. Hold on to what you have, so that no one will take your crown. The one who is victorious I will make a pillar in the temple of my God. Never again will they leave it.  I will write on them the name of my God and the name of the city of my God, the new Jerusalem, which is coming down out of heaven from my God; and I will also write on them my new name. Whoever has ears, let them hear what the Spirit says to the churches."

We need not be anxious or fearful of the end times.  God is faithful.  He will not fail us.
