1 Corinthians 7:7 KJV
For I would that all men were even as I myself. But every man hath his proper gift of God, one after this manner, and another after that.
Here is a marvelous gift; the Apostle is so content in the life that he has, in the state in which he finds himself that it would be his desire that all men find themselves in the same place.
The subject is marriage and it is deduced that Paul was, at this time, single. Whether he had ever been married is mere speculation. Nothing in the Bible indicates that he had but that is neither here nor there. Paul's situation in life is such that he would encourage any man to follow his path.
Now that is a place every Christian ought to go. It should be our desire to so follow Christ and so find in Him our completeness that, whatever our circumstances we could say to others, "I could wish your life was just like mine."
That particular place can only come from fellowship with the Lord. We are all different with varying strengths and weaknesses and interests and spiritual gifts, but we can all be content and we can all fellowship with Christ.
I would that all men had that wonderful fellowship with God.
