Sermon on the Mount: Matthew 5:31-32

It has also been said, Whoever divorces his wife must give her a certificate of divorce. But I tell you, Whoever dismisses and repudiates and divorces his wife, except on the grounds of unfaithfulness (sexual immorality), causes her to commit adultery, and whoever marries a woman who has been divorced commits adultery. Matthew 5:31-32

For if you forgive people their trespasses [their reckless and willful sins, leaving them, letting them go, and giving up resentment], your heavenly Father will also forgive you. Matthew 6:14

Then Peter came up to Him and said, Lord, how many times may my brother sin against me and I forgive him and let it go? [As many as] up to seven times? Jesus answered him, I tell you, not up to seven times, but seventy times seven! Matthew 18:21-22

For it is by free grace (God’s unmerited favor) that you are saved (delivered from judgment and made partakers of Christ’s salvation) through [your] faith. And this [salvation] is not of yourselves [of your own doing, it came not through your own striving], but it is the gift of God; Not because of works [not the fulfillment of the Law’s demands], lest any man should boast. [It is not the result of what anyone can possibly do, so no one can pride himself in it or take glory to himself.] Ephesians 2:8-9

And if any woman has an unbelieving husband and he consents to live with her, she should not leave or divorce him. For the unbelieving husband is set apart (separated, withdrawn from heathen contamination, and affiliated with the Christian people) by union with his consecrated (set-apart) wife, and the unbelieving wife is set apart and separated through union with her consecrated husband. Otherwise your children would be unclean (unblessed heathen, [a]outside the Christian covenant), but as it is they are prepared for God [pure and clean]. 1 Corinthians 7:13-14

[Now having received the Holy Spirit, and being led and directed by Him] if you forgive the sins of anyone, they are forgiven; if you retain the sins of anyone, they are retained. John 20:23
