are they different in terms of we are saved by grace through faith, not by works so that no man can boast?
If we could make ourselves live as God's people by keeping the law, then Jesus would not need to come, but we couldn't... or rather.. not even God's chosen people couldn't do it. Some christians think they can make themselves good by making promises to be a good husbands and a good fathers, but they will fail... the promises will only make them look worse.. as promise breakers.
Galatians 3: 21Is the law then against the promises of God? God forbid: for if there had been a law given which could have given life, verily righteousness should have been by the law. 22But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.23But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed. 24Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith. 25But after that faith is come, we are no longer under a schoolmaster. 26For ye are all the children of God by faith in Christ Jesus.
So now.. we live by faith in the Son of God to help us to live as His as we are His, bought with a price and sealed with that spirit of adoption. Jesus will help those christians to be good husbands and good fathers and good wives and good mothers without the deeds of the law of doing the best they can. but by faith in the Son of God.
Galatians 2:20I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
