You don't have to "know" how to pray, or even pray a certain way. God hears all prayers; big and small ones. Not everyone does pray, and I used to not pray. I just did not want to pray. I didn't think it was important, but I realize now that it is; especially for those who are sick or hurting and may need prayers in their life. I, myself, don't "know" how to pray, but I just talk to God about whatever is on my heart. There is no certain way or certain things to say. Just talk to God; it doesn't matter what it is about. Dear Lord, Please help all the lost to seek you and find you, and get them to follow your ways that you have in store for them. I pray that you place your guiding hand on them to put them on the correct paths of life. Amen
