For if these qualities are yours and are increasing, they render you neither useless nor unfruitful in the true knowledge of our Lord Jesus Christ. For he who lacks these qualities is blind or short-sighted, having forgotten his purification from his former sins. (2 Peter 1:8-9 NASB)

Listening through an audio version of John MacArthur's book "Twelve Ordinary Men" had one thing about Peter stick out to me. Primarily that he spoke from experience. This same man who promised never to forsake Christ (and swung a sword to prove it) was proved a liar hours later by a servant girl asking him for the truth only to give a confident, Spirit-filled sermon to those accusing them of being drunks weeks later. Not a man of knowledge or self-control (v7), Christ used him mightily because he was not gifted, but that he gave himself to be changed and let the truth increase in and through him.

If ought to be moving toward something greater. FROM who I was, FROM who I have been TOWARD the Spirit-Filled, Christ-like life that God has in store for me.
