The fear of the Lord is
the beginning of knowledge: but
fools despise wisdom and instruction. - Proverbs 1:7
Fear in this context does not mean being afraid of or having anxiety about God, but having a holy reverence of God. Americans have forsaken the fear of God.
I hear people say that we need to pray for our country to recover before it's too late, as if it's only unbelievers, not Christians, that need to get right with God. We do need to pray for our country, and after we're done praying we also need to get up and do something about it, instead of sitting on the couch waiting for someone other than ourselves (such as a politician) to take action. As hard as we try, we should not and cannot outsource the Great Commission.
