'I will trust in the Lord' lyrics
I will trust in the Lord, I will trust in the Lord, I will trust in the Lord till I die. I will trust in the Lord, I will trust in the Lord, I will trust in the Lord till I die.
2 I'm going to watch, fight, and pray, I'm going to watch, fight, and pray, I'm going to watch, fight, and pray till I die. I'm going to watch, fight, and pray, I'm going to watch, fight, and pray, I'm going to watch, fight, and pray till I die.
3 I'm going to treat ev'rybody right, I'm going to treat ev'rybody right, I'm going to treat ev'rybody right till I die. I'm going to treat ev'rybody right, I'm going to treat ev'rybody right, I'm going to treat ev'rybody right till I die.
4 I'm going to stay on my bended knees, I'm going to stay on my bended knees, I'm going to stay on my bended knees till I die. I'm going to stay on my bended knees, I'm going to stay on my bended knees, I'm going to stay on my bended knees till I die.
