"Proclaim the power of God, whose majesty is over Israel, whose power is in the skies. You are awesome, O God, in your sanctuary; the God of Israel gives power and strength to his people." -- Psalm 68:34-35
While in college, I worked as a security guard. One night I was alone in a small guard booth during a very heavy rainstorm. At one point my attention was drawn to the loud sound of an oncoming freight train. Since we had tracks nearby I gave it little thought until the next morning. I then discovered that a tornado had touched down just beyond our parking lot, right in line with the guard booth. On the night before, I had heard God's power in the skies.
The Fujita Tornado Damage Scale tells us that tornadoes can reach the strength of 318 miles an hour. These are F5 storms and some refer to them as "the finger of God". During touchdowns in populated areas such power will be devastating. But, what happens when a believer experiences the "finger of God" in their heart? God's power in the skies becomes power in their lives.
My friend, why do you say that the task is too great for you? How is it that you retreat in the face of spiritual challenges? Have you not heard? Do you not know? The God of Israel, whose power is in the skies, gives power and strength to his people! "Finally, be strong in the Lord and in his mighty power." -Ephesians 6:10
