The truth is, our sin is so vile, so wicked, so wretched, so full of anti-God-self-love, that God’s forgiveness of us at the expense of His One and Only Beloved Son should put us into a state of utter shock and disbelief. But if you don’t think your sin is that bad, then God’s grace toward you won’t be that good. And I think this is where other good things (like marriage) creep in and start to look a little more appealing than a right relationship with God.
If you are not shocked that God has offered you a right relationship with Him, then you likely don’t think you’re a very bad sinner. Does the above description of sin sound extreme to you? Then you likely have too low a view of your sin. Or you have excused your sin because of circumstances or by comparing yourself to others. And so long as knowing God is not that impressive to you, you’ll always be looking to something else for deep and abiding joy.
