Book of Acts 3:1 says "now Peter and John went up into the temple of the ninth hour of Prayer". This was time / hour of Prayer. They saw and healed a lame Miraculously.

Your Prayer time is the hour of Your Miracle. So don't let it gone in vain. Just go and sat back in Your Prayer room and look unto God hoping to receive something like this lame man.

May be you prayed for long time and nothing had happened till today. But just meditate on the Bible it took 7 days and 7 rounds to pull down the wall of Jericho (Joshua 5-6). It took 7 dive to clean Naaman Leper (2Kings 5). Yes, I push you to Pray one more time in this same anointing.
