I think the most difficult thing for me to grasp is that God is agape. He is love for the ugly people. I don't meant the typical Christian sense of the word ugly which is really false humility. I literally mean ugly. Absolutely wretched, miserable and completely absent of any hint or sign of beauty.
I absolutely cannot understand how God doesn't hate me when I sin. If not for His grace, I would be swallowed up by my sin and wretchedness. How could He ever tell me, "Well done, good and faithful servant"? I am absolutely nothing without Him. I feel at times exactly like Mephibosheth a lot of the time. "I'm just a dead dog, Lord". Definitely not one anyone could say was good and faithful.
Worthy is the Lamb!! Jesus gets all the glory!! I have worth because He has loved me. I am what I am by the grace of God. My crown of righteousness will most definitely be thrown at His feet. He is the One who has made me worthy and given me any reason for existence.
