2 Peter 2:4 For if God did not spare angels when they sinned, but sent them to hell, putting them in chains of darkness to be held for judgement; David continues the study in 2 Peter 2 (moving onto chapter 3 tomorrow). False teachers wreak havoc and this goes on today as we find ourselves in the last days. David urges us to pray about where best to sow our tithes. Many false prophets exist ; amongst the worst of these in recent times was Jim Jones and his ill-fated People's Temple where 900 people died in a mass suicide. Lean heavily on God's word the Bible and don't get lead astray Beloved.
