Jewish-background Christians found it difficult to believe that the law given to Moses was not God’s ultimate authority.  They could not see how Jesus had greater authority.  Paul explained that God’s promise to Abraham was an unconditional covenant which would be fulfilled by Jesus, whereas the law came almost 500 years later and was a conditional covenant.  The condition for the law was that God would bless His people if they were obedient but would curse them for disobedience.  You can read the details in Deuteronomy 28:1-68.
 
God’s law given to Moses was a temporary way of enabling people to know what pleased God.  It told God’s people how to live harmoniously and not get entangled with the false religions around them.  But the unconditional covenant to Abraham came first, and pointed to Jesus who would fulfil all God’s promises for His people (2 Corinthians 1:20), because they could never satisfy the demands of the law themselves.  That covenant was given because of God’s grace.  It is the difference between working hard to get paid, and receiving a gift which has been given in love.
 
Many people today still believe that they have to earn God’s favour; thinking that unless they are good enough, God will not bless them.  Those people need to discover the grace of God.  John 3:16 says, “For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.”

Eternal life can never be earned, but it is freely given to those who believe in Jesus (Ephesians 2:8-9).  If you are already a believer, choose to thank God today for His grace, marvel at His love, be comforted by His forgiveness, be strengthened by His presence in your life and live to please Him to show that you are truly grateful.  If you are not confident that God has accepted you, please watch the video at www.crosscheck.org.uk to understand how much God loves you and why Jesus has been punished instead of you.
