Okay it doesn't matter what time you pray, God will acknowledge your prayers. Because it's the thought that counts. When you are praying, you know what it is your praying about, and we have different kinds of prayers. We have asking prayers, healing prayers and warfare. So for me i feel all the other prayers are okay to pray during the day, but when it comes to warfare prayers it is better to do them at night. We are told that the devil watches our every move, he waits for every opportunity to get hold of people who are vulnerable, and at night between 12 midnight and 3am in the morning, that is when he is most active. So when you are praying in thr spirit, and you are binding spirits what better time to do it than during the day. It is at this time when there are no distractions, or any kind of interruptions, so it's easier to pray.
