Waiting on The Lord is never easy, but ALWAYS necessary. God doesn't show up just because we ask Him to. He shows up when He is needed AND trusted most. When you are at the end of your rope, and when there is nowhere left to turn, and no one left to turn to, THAT is when God shows up and shows out!
To wait on God is an event that happens numerous times in the Bible, and always with positive results. The Bible doesn't ask you to "wait" so much as it encourages "patience" during tribulation.
Wait. God is ALWAYS on time!
