With regard to remarriage, the scripture reads as follows:
1 Cor. 7. 39 A wife is bound as long as her husband lives; But when her husband has died, she has the freedom to marry who she wants, only in the Lord. 40 But happier is she if she becomes as she is, in my opinion; But I also believe to have the Spirit of God.
This has nothing to do with my personal opinions, but what God's word tells us how believers should live. And as a preacher, one is a pattern for the flock.
Psalm 119. 8 I will keep your statutes; You can not just leave me!
Unfortunately, here was a preacher who was not so close to the word of God in his own life.
