In this passage, the apostle Paul does not say, “Pray and worry.” Instead, he is saying “Pray and don’t worry.” Why are we to pray and not worry? Because prayer is an important way we cast our care upon the Lord. Prayer is what opens the door for God to work in our lives and the lives of other people.
When Satan tries to give us something to worry about, we can turn and give that care to God. If we pray about something and then keep on worrying about it, we are mixing a positive and a negative. The two cancel each other out so that we end up right back where we started—at zero.
Prayer is a positive force; worry is a negative force. The Lord has shown me the reason many people operate at zero power spiritually is that they cancel out their positive prayer power by giving in to the negative power of worry.
As long as we are worrying, we are not trusting God. It is only by trusting, by having faith and confidence in the Lord, that we are able to enter into His rest and enjoy the peace that transcends all understanding.
