Prayer is an unbelievably important part of life. It is the primary means by which we communicate with God. There are other means of communication, but prayer directly connects us with our Father. We are able to express things to Him that we feel we can not tell anyone else. He is always listening, even when we are not kneeling with our eyes closed and hands clasped.
Sometimes, we avoid praying because we do not know what to say. This is an easy trap to fall into, but God knows why we do this, and He is not upset. Because there are other ways of connecting with God besides prayer, we are still able to have a fulfilling relationship with God without being in a state of constant, traditional prayer.
