These words were spoken to Israel just before God set them free from slavery in the land of Egypt. They were about to start out on a journey with the Lord to the Promised Land. Apparently He wanted them to understand it was a new beginning he was giving them, so he designated that time as "the first month of the year".
This is a lesson to us about the way to a new beginning and a new life. We get excited about a new year, but the only way we can truly start a new life is with God. Without the Lord the new year will be simply more of the same. Our lives will repeat and relive their old patterns and problems.
It is a central fact of Bible Christianity that God offers a new life through Jesus Christ. The very first man Adam fell into sin and ruined the life that he had. He became sinful, selfish, and subject to death. That life is the one we have had passed down to us as his descendants. We were born self-centered (without God), sinful and dying. All men need to receive a new life.
Jesus Christ came to take care of the root problem of sin by paying its penalty with his own death on the cross. He suffered so we could be spared and would not have to suffer eternally in hell. The same Saviour rose from the dead and offers the very new life we need to all that will trust in Him. It is a life that is seen in a changed heart and a changed lifestyle. It is a life that suits us for eternity in heaven when we leave this world. It is a life that is received freely by turning your past over to Him and trusting in Jesus Christ personally as Lord and Saviour.
