'Proportion' in the Bible
To one he gave five talents, to another, two, and to another, one, each according to his own ability; and then he went on his journey.
So the disciples decided to send a contribution, each according to his individual ability, to the believers who lived in Judea.
But the free gift [of God] is not like the trespass [because the gift of grace overwhelms the fall of man]. For if many died by one man’s trespass [Adam’s sin], much more [abundantly] did God’s grace and the gift [that comes] by the grace of the one Man, Jesus Christ, overflow to [benefit] the many.
Since we have gifts that differ according to the grace given to us, each of us is to use them accordingly: if [someone has the gift of] prophecy, [let him speak a new message from God to His people] in proportion to the faith possessed;
On the first day of every week each one of you is to put something aside, in proportion to his prosperity, and save it so that no collections [will need to] be made when I come.
For if the eagerness [to give] is there, it is acceptable according to what one has, not according to what he does not have.
Yet grace [God’s undeserved favor] was given to each one of us [not indiscriminately, but in different ways] in proportion to the measure of Christ’s [rich and abundant] gift.
