Romans 12:3 - 8 - For I say, through the grace that was given me, to every man who is among you, not to think of himself more highly than he ought to think; but to think reasonably, as God has apportioned to each person a measure of faith. For even as we have many members in one body, and all the members don't have the same function, so we, who are many, are one body in Christ, and individually members one of another. Having gifts differing according to the grace that was given to us, if prophecy, let us prophesy according to the proportion of our faith; or service, let us give ourselves to service; or he who teaches, to his teaching; or he who exhorts, to his exhorting: he who gives, let him do it with liberality; he who rules, with diligence; he who shows mercy, with cheerfulness.
Matthew 5:42 - Give to him who asks you, and don't turn away him who desires to borrow from you.
Romans 14:23 - But he who doubts is condemned if he eats, because it isn't of faith; and whatever is not of faith is sin.
Acts 27:25 - Therefore, sirs, cheer up! For I believe God, that it will be just as it has been spoken to me.
Romans 4:9 - Is this blessing then pronounced on the circumcised, or on the uncircumcised also? For we say that faith was accounted to Abraham for righteousness.
