1 Corinthians 7:22

Called in the Lord; converted.

Is the Lord's freeman; through divine power and grace, he is delivered from the condemnation and bondage of sin; and under the teaching of the Holy Ghost pursues his own free choice, cheerfully, as an affectionate child, doing the will of his Father in heaven.

Is Christ's servant; not an involuntary, but a willing servant; who chooses to be his, delights in his laws, and is to receive a great reward.
