The answer from God’s word:
“Prayer is one of the ways in which man cooperates with God, it is a means by which man calls upon God, and it is the process by which man is touched by God’s Spirit. It can be said that those who are without prayer are dead ones without spirit, proof that they lack the faculties to be touched by God. Without prayer, they are unable to attain a normal spiritual life, much less are they able to follow the work of the Holy Spirit; without prayer, they sever their relationship with God, and are incapable of receiving God’s approval. Being someone who believes in God, the more you pray, the more you are touched by God. Such people have greater resolution and are more able to receive the latest enlightenment from God; as a result, only people like this can be made perfect as soon as possible by the Holy Spirit.”
