Your zealousness for Jesus will be in direct proportion to your communication with Jesus. Prayer is like quietly opening a door and slipping into the very presence of God and there in the stillness, listen to his voice, and perhaps petition or just admire. Just to silently be there in his presence is prayer. The world is vanquished when you zoom in and concentrate your heart on Jesus. Some pray about great problems.
Some people pray over lottery tickets.
I suppose some only pray at night because they feel the rates are cheaper. Some pray and then worry. We should pray to get to know Jesus more fully. Prayer is powerful. The only way it works is if we believe in it and take advantage of it.
