Take pains (meditate upon) with these things; be absorbed (give thyself wholly) in them, so that your progress will be evident to all. — 1 Timothy 4:15 NASB (KJV)

1. constantly nourish on the words of faith and sound doctrine (v.6)
2. discipline yourself for the purpose of godliness (v.7)
3. fix your hope on the living God (v.10)
So that your progress will be evident to all:

Thy friends in thy conduct,
His likeness shall see.
Continually seeking Him,
