Paul exhorts Christians to live in pleasing holiness before Christ, that is to say in a living sacrifice we must offer our bodies, everything we are every day to God, as an act of adoration
Paul invites us to live with humility and faith in our Christian relationships, just as the body is made up of several members, each with a different function, the church is a body with many members, each with individual roles and responsibilities, but all intimately related as a unit in Christ. We should not consider ourselves in a superior position, nor diminish the role of others.
Paul refers to his own function in the body as an apostle with authority for the grace that is given to me, the measure of faith does not allude to the faith of salvation, but to the faith that accompanies receiving and using the gifts that God gives us. gives.
"The measure of faith" that the Lord offers corresponds to the functions he assigns as creator and redeemer.
Our different gifts and abilities should make us more loving and dependent on each other, and, therefore, more united as a body in Christ.
