Pray for O’s conversion.
Praying for him to receive his reward is, IMO, the first step. For him to acknowledge and surrender to God requires a tremendous amount of realizations first, which in his present position is highly unlikely. But that would be fine too - very good - but if he surrenders to God, we would know because he would publicly admit his wrongdoing and step down from the Presidency.
I pray for his immediate “conversion” into a lowly private citizen, daily.
