'Unapproved' in the Bible

But [like a boxer] I strictly discipline my body and make it my slave, so that, after I have preached [the gospel] to others, I myself will not somehow be disqualified [as unfit for service].

But I pray to God that you may do nothing wrong. Not so that we [and our teaching] may appear to be approved, but that you may continue doing what is right, even though we [by comparison] may seem to have failed.

We are glad when we are weak [since God’s power comes freely through us], but you [by comparison] are strong. We also pray for this, that you be made complete [fully restored, growing and maturing in godly character and spirit—pleasing your heavenly Father by the life you live].
