Love and Dissapointment

So, the Bible says that men will dissapoint you, (and me), but that God will not let us down. I must believe this, because in my life I so often lift people up and I do esteem them higher than myself, and that is something the Word teaches us to do. Yet, when someone I love sins... whether against me, or not, though it affects me, I choose to look to the Lord for the answers. Sometimes, I think that maybe He lets experience this, so that we will not put confidence in man, or flesh, but in Him. It's one of the hardest things to accept in life, that we are vulnerable to each other- because it opens us up, and also it makes us responsible.
