Prayer is the act of wanting to be a part of God's existence. We talk to the ones we love to be a part of their lives. God wants to be a part of our lives. When he created the garden he walked with us daily. He talked with us daily. Prayer is the closest we can come to regaining what we lost there. We can't physically walk with God at this time but we can still talk to Him. People who say they do not need to pray sadden me. Don't they want to talk to the one they believe in and love.
This isn't even getting into the super natural part of prayer. Some people are called to be prayer warriors. And their prayers are answered in amazing ways. That is not my gift. I have a hard time setting aside chunks of time specifically for prayer. Personal weakness. BUT- I talk to God throughout the day despite. I want to know what is going on in my child's life but I want to know from her. Why deny God that? I'm his kid ultimately. God create us to be with HIM, to walk with Him, to talk with HIM- why not do it?
Not praying, I fear distances you from God. It smothers your emotional understanding of God. When I have a difficult time praying and fail for a period of time- I feel it in my faith. It is very lonely for me. And my understanding of my faith twists. Of course this is my personal experience.
Prayer is communication. So communicate.
