2 Corinthians 5:12

Are we beginning to commend ourselves again? Or do we need, as some, letters of commendation to you or from you?

but we have renounced the hidden things of shame, not walking in craftiness or adulterating the word of God, but by the manifestation of truth commending ourselves to every man’s conscience in the sight of God.

You are looking at things as they are outwardly. If anyone is confident in himself that he is Christ’s, let him consider this again within himself, that just as he is Christ’s, so also are we.

so that your reason for boasting may abound in Christ Jesus in me, through my coming to you again.
