Many of them would reply that they had prayed Obama resign, die, lose re-election, not cause lasting harm, or otherwise prayed every which way they could pray about him without actually praying for him.
Having mentioned on social media last week that people complaining about President Trump should pray for him, some demanded to know if I had ever done the same for Barack Obama. Yes and repeatedly over the course of eight years. Others, however, did exactly as some had dome to Barack Obama. They prayed all sorts of things about the President, but did not pray for the President.
If you are a Christian, scripture commands you to pray for the President. You should pray for his protection, his well being, that God grants him wisdom, that he is a faithful instrument of God’s will, that he glorifies God in all he does, etc. You are to pray God’s blessings on the President and ask God to be with the President. Yes, you can pray that God turn the President’s heart, but pray for him too. Scripture commands it.
Put bluntly, if you cannot bring yourself to pray positively for the President, you are no better than your view of the President. Pray for his safety, his leadership, his wisdom, his family, and that he is surrounded with capable people. Again, this is what scripture says to do. There is no reason to obfuscate it or try to weasel your way out of it.
Pray for the President and pray sincerely.
