If you can stay up all night to watch a favourite series, you can stay up all night to pray. The reason why it seems easier to do the former than the latter is because prayer was not designed in such a way that the machinations of the human flesh can power it. If you must pray, you must be helped, particularly because the flesh will actively war against the spirit to ensure you do not pray. If you are watching a movie late at night you may sense some resistance from your spirit but it is usually not forceful. But when the flesh resists your Spirit you will know it. That is why you cannot pray without the help of the Spirit. Have you noticed that people usually struggle to stay awake during a night vigil when prayer or bible study is going on but if you were to close the service so that people can sleep, you will notice that half the people who were struggling to stay awake would be wide awake gisting until daylight? The spirit realm is not accessible to your natural faculties and so you must be helped. Apart from the infirmity of your flesh, you also are laden with the infirmity of knowledge. So let us assume you are able to take care of the issue of sleep by some natural means so that you can be awake all night, you will still be faced with a whole new difficulty; knowing what to pray for as you ought. I used to be in a relationship back then and at some point things got really bad that we could be together on a date and there is nothing to talk about. We were both frustrated, people in love should have a natural chemistry such that discussions are not mechanical. But I was the problem, I did not know what to say as I ought. The man who wants to pray would also realize that he is dealing with a Spirit who operates on a very different frequency from him and one who you cannot summon but makes himself known at his time. From the onset the man is heavily disadvantaged. It is why really the only prayer you can initially pray when you wake up at night is "help me Holy Ghost". Just keep saying that for 1 hour. Then for 1 week, Then for 1 month. Keep your prayer watches. You will see that the Holy Spirit is drawn to a broken and a contrite spirit. There is nothing that attracts him better than a man who caves to his vulnerabilities before the consciousness of his Divine abilities. "Help me Holy Ghost" is a valid prayer. Pray it and see how your life will be transformed. The thing with the prayer is that it can fit into any situation. Are you mourning? Help me Holy Ghost. Are you broke? Help me Holy Ghost. Are you battling an addiction? Help me Holy Ghost. You cannot pray? Help me Holy Ghost. You eat too much? Help me Holy Ghost. You are battling with ungodly telegram channels? Help me Holy Ghost.
