God gave Moses the law, and the children of Israel were expected to live by the law every day, one good act today had to be maintained throughout their lives for them to be counted righteous before God.
Jesus came and fulfilled the law and abolished it. In this new dispensation, you don’t get righteous by doing the law, because there is no law, the bible says the law was not made for a righteous man, 1Timothy 1:9 and every Christian has been made righteous in Christ Jesus.
Remember in other for the Christian to be righteous he had to believe in his heart that God raised Jesus from the dead and confess the Lordship of Jesus.
For Moses describeth the righteousness which is of the law, That the man which doeth those things shall live by them.But the righteousness which is of faith speaketh…
This scripture tells us that in the old testament, to be righteous you had to do the law, but in Christ Jesus, we don’t do the law, we speak the word. Just like in the old testament you had to do the law everyday, in this dispensation you have to speak the word everyday.
…for he hath said, I will never leave thee, nor forsake thee. So that we may boldly say, The Lord is my helper, and I will not fear what man shall do unto me.
Notice the bible said God said so that we may boldly say, he didn’t say God said and now we boldly say, because that was not what he meant to say, showing us the reason for the word, God gave us his word to see what he has said concerning us and to declare boldly what he has said in our lives.
Every believer is a talker, Jesus said “I am from above… I and my Father are one” Jesus was a man of confessions and he has shown us by his word that we ought to speak the word everyday. Learn to do that and see the improvement in your life.
