Romans 14 teaches us not to be critical or cause there to be any stumbling blocks in a weaker brother's way. We are not to condemn another servant of God due to a disagreement, but allow God to show them what is right. We can trust that "the Lord is able to make them stand" (v.4). Paul says, "So then we pursue the things which make for peace and the building up of one another" (v.19). Romans 15 teaches then, to help bear the weaknesses of a brother, for his edification. Accept one another, for the united purpose of bringing praise and glory to God for His grace and mercy. Paul says to boast together only in Christ's work in you, and strive together in prayer , that God might "fill you with all joy and peace in believing, so that you will abound in hope by the power of the Holy Spirit".
