Doubts can overwhelm us with fear, When we ask God for something, we must show him that we are patient and believe he will do what he promised to do, according to his will. If we are struggling with patience, we continue to find ourselves calling on God to save us from the very thing he instructed us to stay away from. John 1:6 says, "But let him ask in faith, nothing wavering, for he that wavereth is like a wave of the sea, driven with the wind and tossed". Overcome doubt with faith.
