New King James Version (NKJV)
Romans 14
22 Do you have faith? Have it to yourself before God. Happy is he who does not condemn himself in what he approves.
23 But he who doubts is condemned if he eats, because he does not eat from faith; for whatever is not from faith is sin.
Romans 15
1 We then who are strong ought to bear with the scruples of the weak, and not to please ourselves.
2 Let each of us please his neighbor for his good, leading to edification.
3 For even Christ did not please Himself; but as it is written, "The reproaches of those who reproached You fell on Me."
4 For whatever things were written before were written for our learning, that we through the patience and comfort of the Scriptures might have hope.
5 Now may the God of patience and comfort grant you to be like-minded toward one another, according to Christ Jesus,
6 that you may with one mind and one mouth glorify the God and Father of our Lord Jesus Christ.
7 Therefore receive one another, just as Christ also received us, to the glory of God.
8 Now I say that Jesus Christ has become a servant to the circumcision for the truth of God, to confirm the promises made to the fathers,
9 and that the Gentiles might glorify God for His mercy, as it is written: "For this reason I will confess to You among the Gentiles, And sing to Your name."
