1) There are two types of sin: sins of commission which go against God's commands, and sins of omission which involve not doing what God has commanded. 2) There are also two types of sinners: those who sin out of ignorance, and those who sin willfully despite knowing God's commands. 3) There are two types of service to God: giving Him what is left over after other priorities, or making Him the top priority and seeking His kingdom first in all things. The talk focuses on overcoming sins of omission by keeping God as the top throne of one's heart.
