Bearing the pathological partner
First Peter 3:1–6 gives guidance for you in trying to win a husband who does not obey the Word. It doesn’t answer every question. It will leave questions unanswered, but the Lord has given it to us, and it is a gift to us in marriage.
2) Second encouragement. The Lord promises to give you all the grace you need to be pleasing to him yourself. “And God is able to make all grace abound to you, so that having all sufficiency in all things at all times, you may abound in every good work” (2 Corinthians 9:8). Whatever your husband does, thinks, or feels, God looks to you alone for whether you are walking in sin — not your husband.
3) Marriage is a parable of covenant faithfulness, not covenant bliss. Your faithfulness to your vows is pleasing to the Lord no matter how much sadness is in your heart or in his heart. It tells the truth. This covenant keeping, your marriage, is telling the truth about Christ and his church as a covenant-keeping Christ and church.
4) Things can change. Even after many years, yes they can. So now unto him who is able to do far more abundantly than you ask or think according to the power at work within us (Ephesians 3:20). So don’t make your faithfulness depend on your husband’s change, but do keep hoping and praying for it. Keep knocking on the door of heaven.
5) And the last encouragement I would give is this: Even if your marriage falls short of your hopes to the end (and what marriage doesn’t?), God will reward your faithfulness in the age to come a thousand-fold. “Whatever good anyone does, this he will receive back from the Lord” (Ephesians 6:8). Your husband and your friends may have no idea how many sacrifices you have made in order to love your husband as well as you can. But God knows every single one of them, and he says you will be repaid. All our trials are working for us an eternal weight of glory (2 Corinthians 4:17).
