This is a great excerpt from Henry Blackaby’s Experiencing God on why God gives us commands at all (21).
“God has given His commands so you may prosper and live life to its fullest measure. Let me give you an example. Supose the Lord says, ‘I have a gift for you- a beautiful, wonderful expression of what love is. I will provide you with a spouse- a husband or awife.
Your relationship with this person will bring out the very best in you. It will give you an opportunity to experience some of the deepest and most meaningful expressions of human love. That individual will release in you some wonderful things, affirm some things in you, and be there to strengthen you when you lose heart.
Within that relationship, your mate will love you, believe in you, and trust you. Out of that relationship I will bless the two of you with children, and those children will sit on your knees and say, ‘Daddy, I love you.’
But then He says, ‘You shall not commit adultery’ (Matt 5:27). Is that command to limit or restrict you? [Or] is it to protect and free you to experience love at its human best. What happens if you break the command and commit adultery?
The love relationship is ruptured between husband and wife. Trust is gone. Hurt sets in. Guilt and bitterness creep in. Even the children begin to respond differently. Scars may severely limit the future dimension of love you could have experienced together.
God’s commands are designed to guide you to life’s very best.”
God is good, and loving.
