Continue in prayer, and watch in the same with thanksgiving. (Colossians 4:2). Praying to God or communing with Him is an all day occurrence. You should be eager to talk to your Father in heaven. Not always to ask Him of anything, but to offer Him thanksgiving, too!!
I want you to remember that when you pray to your Father, which is in heaven that he hears you that very instant you pray. I have heard some say God is not hard of hearing, so you do not have to repeat yourself.... That is a true statement, but most of the time when you pray...you may be asking for the same thing,,,,but at times you are asking in a different way. God answers your prayers instantaneously, intermittently, or gradually.
It is not so much that you are repeating yourself, but that you are taking the time to pray. In most cases you are interrupted and have to start over. The beauty of that is God always, always remembers where you left off in the conversation. If you are praying to God for a BIG thing to happen, do not forget to thank Him for the small things that are happening to assure the BIG one manifests.
