A pinnacle moment is when you are tempted to do something foolish and you use God's word, and the character of our loving God to justify it.
When we do this we test God. Jesus said, "we should not test God."
Pinnacle moments are usually scary places where you feel like jumping, leaping to your death, being destructive is your only recourse. To test God rather than to stay firm and grow deeper in your trust of God is a great temptation.
Don't Jump! Take a knee, get back from the edge, breathe deeply, and know God does not reward foolishness, but faithfulness!
No murmuring, No arguing with God, and He is not to blame for the wilderness you are in. This is a test, it is only a test.
God's purpose is to see if you truly mean to follow Him and His way!
