The first three categories of vessels in God's House: 1. The Questionable -Those who possess a sinful past or certain behavior that are considered 'not qualified' according to human standards (eg. Former prostitutes Rahab and Tamar, adulterous Bathsheba, impulsive Peter etc)2. The Hesitant vessel - Those who want to do God's work, but are held back by fear and doubt (eg. Moses was worried about His speech , Jeremiah about his age) 3. The Resistant vessel - Those who resist the work of God when he call (eg. Jonah run from God's presence).
