Titus 3:8
Faithful saying .. trustworthy. [cf NEB] If the Faithful saying v. 4-5, or v.7, or v. 8? Most say vs 4-7.
Affirm constantly .. Be insistent in these teaching, Affirm Truth. Not in sense of continually, but uniformily.
Believers maintain good works. Ephesians 2:10
Good works .. honorable occupation, etc. maintain = occupy self.
