'Work' in the Bible

And for this further reason we render unceasing thanks to God, that when you received God's Message from our lips, it was as no mere message from men that you embraced it, but as--what it really is--God's Message, which also does its work in the hearts of you who believe.

Now we beg you, brethren, to show respect for those who labour among you and are your leaders in Christian work, and are your advisers;

Faithful is He who calls you, and He will also perfect His work.
