It is not the length of time you pray that matters, for some it is only a few moments and others a while longer. The Lord isn't impressed on how long you pray, only the sincerity of your prayers. Dear one, Jesus IS there with you when you pray; we not always "feel" Him there, but He is. The Bible tells us that if we draw near to God, then He will draw near to us. If you want more of Jesus, then spend time reading His holy word, pray, and then worship Him. He is a gentleman and He will not force Himself on anyone; we either choose to love and serve Him or not. It is really very simple. The enemy of your soul does not want you to get closer to God; he will try his best to distract you. Stay focused on the Lord. He wants a personal relationship with you; you are His beloved child if you have asked Him into your heart to be your Lord and Saviour. God bless you!
