'Rendering' in the Bible

It was revealed to them that their services [their prophecies regarding grace] were not [meant] for themselves and their time, but for you, in these things [the death, resurrection, and glorification of Jesus Christ] which have now been told to you by those who preached the gospel to you by the [power of the] Holy Spirit [who was] sent from heaven. Into these things even the angels long to look.

Not rendering evil for evil, or railing for railing: but contrariwise blessing; knowing that ye are thereunto called, that ye should inherit a blessing.
