I know people who have said: ‘I would follow Christ, but I do not think I can keep it up. I do not trust myself. I think he’d get tired of my failures.’ Please look at him in the garden. Look what his love for you has already enabled him to endure for you. If he had turned away from suffering and the cross, we would have been lost, but he didn’t do that. Hell came down on him, and he would not let go of us. His love for us has already taken everything that the universe could throw at it and it held fast— and you think that you are somehow going to upset him? Is Jesus going to look at you and say, ‘Well, that does it! Infinite existential torment was one thing, but I can only take so much!’? If this suffering did not make him give up on us, nothing will. So Paul can essentially say, ‘Nothing can separate us from the love of Christ’ (Romans 8: 38– 39). The Lord says, ‘I will never leave you; never will I forsake you’ (Hebrews 13: 5).
This is the love you have been looking for all of your life. This is the only love that can’t let you down. This is bombproof love. Not friend-love, not personal acclaim, not married love, and not even romantic love — it is this love that you are after, underneath all your pursuit of those others. And if this love of active obedience is an active reality in your life, you will be a person of integrity; you will be a person of prayer; you will be kind to people who mistreat you. If you have this love you will be a little more like him. Look at him dying in the dark for you. Let it melt you into his likeness.
