A few months ago, I was having a "discussion" with a fellow pastor about faith and works. When I maintained that the work God wants us to do is "believe" His promises to us, rather than try to work for ourselves, my friend was completely disagreeable. And when I pointed to the fact that God promised Abraham he would have a son, and all Abraham did was believe (see Genesis 15:6), he reminded me of something interesting that I had overlooked. "Abraham didn't simply believe the Lord," he said, "He still had to have sex with Sarah in order for her to get pregnant."
Now, I don't believe the Bible explicitly mentions whether or not this is true, but I don't doubt that it is. But the point that he was making is that God doesn't ask us to only believe, but He tells us that we still have to "work" as well for our own salvation. Even though Abraham believed in the Lord and was righteous because of it, he still had to work, my friend maintains.
I kind of understand - and somewhat agree - with what he is saying. There is no doubt that true followers of Christ "work" when they have faith. You cannot separate faith from works. It's impossible (see James, who has something to say about this).
But something dawned on me a little while later. What my friend calls "work" I would call "pleasure." Do you think that Abraham really thought it was "work" to sleep with Sarah? Hardly! It was pleasure. And that is the precise reality with God. When we come into a heart-experience with Him, and respond by faith, that which we would consider "work" before actually becomes "pleasure." As Paul reminds us, "For it is God who works in you both to will and to do for His good pleasure" (Philippians 2:13). And when we do His pleasure, it becomes our pleasure as well.
Of course, my pastor friend, who is unmarried, may have a hard time understanding this! But, I would dare say, even unmarried people have a good idea about the blissful marital pleasures.
