'Act' in the Bible

But shall not the act of favour be as the offence? For if by the offence of one the many have died, much rather has the grace of God, and the free gift in grace, which is by the one man Jesus Christ, abounded unto the many.

And shall not as by one that has sinned be the gift? For the judgment was of one to condemnation, but the act of favour, of many offences unto justification.

For the wages of sin is death; but the act of favour of God, eternal life in Christ Jesus our Lord.
