The thing about teaching and Teaching is that teaching usually leads back to bad fruit (destruction, dissolution, ownership, lovelessness…) while Teaching always leads to good fruit (Love, generosity, respect, protection…); here’s to view the Teaching according to Jesus:
13:4 Love is always patient and kind; it is never jealous; love is never boastful or conceited; 13:5 it is never rude or selfish; it does not take offence, and is not resentful. 13:6 Love takes no pleasure in other people’s sins but delights in the truth; 13:7 it is always ready to excuse, to trust, to hope, and to endure whatever comes. 13:8 Love does not come to an end. (1 Corinthians)
How can adultery be the key to divorcing one’s spouse?
How can Christ Teach His Followers to sin so that they can join a life of sin.
Rather, look at what is said: 'the one who divorces and remarries another lives in adultery (lives in sin) and the one who marries the person who has divorced another also lives in adultery (lives in sin).
It is good to own up to our failures ("I’m a sinner); it is better to own up to God: Be Holy, for I AM HOLY!
