One of the most important things for Christians is prayer. Prayer is a direct way of communicating with God. We feel closer to him when we pray. Prayer is also, in a way, a coping mechanism, something people do when they feel frustrated, angry, sad, or scared. Praying can help us feel more relaxed and in control of our feelings because we’re having that conversation with God, and that alone often works as a shooting, peaceful and calming aid.
However, praying for peace, love, strength, or health is not the same as praying for faith. Praying for faith is not something the Bible teaches us. Prayer is necessary to grow our faith in our hearts; our prayers are mainly for someone we know and love or for ourselves, not for faith. Understandably, sometimes people may feel like they’re falling out of their faith; they feel the need to pray for faith; however, we must grow our faith by planting the seeds of God’s word in our hearts, God’s himself will be the one who turns those seeds into harvest.
Our faith will grow as we do our part in following God’s precepts. And, as the Bible says, our prayers will only be answered if they’re done with faith. So perhaps your feelings of lack of faith are a sign of a weak life in faith, and to strengthen our faith, we need to build a strong bond with God by having frequent communication with him. Prayer is the only way to build trust and faith. Prayer provides a continual line of communication with God, which is just what we need to get to know him better and build a stronger faith.
And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him. - Hebrews 11:6
