In explaining & summarising Scripture the Heidelberg Catechism addresses the 7th commandment, Thou shalt not commit adultery.Lord’s Day 41.
108. Q. What does the seventh commandment teach us?
A. That all unchastity is accursed of God; and that we must, therefore, detest it from the heart, and live a chaste and continent life both within and outside of holy wedlock.
109. Q. Does God in this commandment forbid nothing more than adultery and such like gross sins?
A. Since our body and soul are both temples of the Holy Spirit, it is his will that we keep both pure and holy; wherefore he forbids all unchaste actions, gestures, words, thoughts, desires, and whatever may entice one thereto.
It’s a big ask & reveals our incapability to fully match it when it comes to the holiness & goodness of God. He who is without sin cast the first stone etc. While the modern world lowers the bar more & more so that you could stumble or be blown across it in the name of freedom, believers in the Lord Jesus Christ are called to aim high. Not in a moralistic righteousness of human attainment & will, but in trusting in the grace & power of Christ who freely gives His Spirit that we may do battle with those things that seek to undo real freedom expressed in human form & that which mirrors God’s ways.
God gives us boundaries for our protection & good. Resist says God, resist. & when you are weak seek Him in prayer, seek Him in His word. Adultery is more than the physical act, it’s much much more & it’s pretty much everywhere…but so is God only more so. Omnipresent & omnipotent.
Psalm 12:6-8. And the words of the LORD are flawless, like silver purified in a crucible, like gold refined seven times. You, LORD, will keep the needy safe and will protect us forever from the wicked, who freely strut about while depravity is honored by the human race.
