Pray for a breathen who is not committing sin unto death, you can not pray for someone who is sinning unto death, when you give a time to breathen to repent but then he or she refuses to change or repent then you expel them from church.
God already knows ours needs so all we have to do is requesting those things from him by prayer and not telling story. Prayer is a request and not stories you tell to God. Like saying blessed Holy Mary mother of Christ prayer for us, God already knows that which is in your heart, all we have to do it to be the one to pray and not commanding mother of God to pray go us. Mary have Dead and haven't raise from the dead, so how can she pray for you Even for the sinners. Still on prayer, like I said before prayer is the way we communicate with God almighty in heaven. By prayer and supplication with Thanksgiving let your request be made know unto God.
As Christian you have to abstain from stealing. You can expel someone who do evil but you will not do the same thing or do those things that you preach against. Before you correct a breathen who commits evil you that is correcting him or her should not commit evil correcting someone who steal.
