Romans 6 1-4 addresses continuing in a known sin after being forgiven. Yes we all will continue to make mistakes and sin but those sins are continually forgiven if your walking in the light. If you are living in willful sin and refuse to repent and turn from it that’s a different situation.Its hard I have many friends that got married early in life and got divorced because they couldn’t get along and later remarried and have a wonderful life with children etc. But it doesn’t change the fact they’re living in adultry according to the word of God.
