Titus 3:4, 7-8, 14

But after that the kindness and love of God our Saviour toward man appeared

that being justified by his grace, we should be made heirs according to the hope of eternal life. This is a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to maintain good works. These things are good and profitable unto men.

And let our's also learn to maintain good works for necessary uses, that they be not unfruitful.
