We have all seen it one time or another. Some have even experienced it personally or with a loved one. The person is on the hospital bed - their heart stops - the staff of nurses and doctors surround the patient - they fire up the defibrillator and someone cries out, "Clear!"
If the procedure works then the patient has been revived. If it doesn't, they proceed on with CPR and if the heart doesn't start back up they continue to use the defibrillator hoping that the patient will be revived.
It is the same with you physically. You had nothing to do with your birth. God breathed into you the breath of life and if your heart were to stop, you can do nothing about it. You would need an intervention to get your heart revived.
But here's the point - it is the same way with us spiritually. The Bible tells us that we were all sinners and we were dead in our trespasses. But God intervened and made us alive in Christ. But somewhere, somehow, at one time or another we have found ourselves to have grown cool. Our spiritual heart isn't beating with health as it had before or maybe it has even stopped. We read more of our Bible, we pray, we go to church, we listen and watch more spiritual programming, and all of those things are good, but it seems as though our spiritual heart is dead.
That's when we need intervention. That's when we need the very One who created us to come and revive us. Just as you couldn't save yourself - you can't revive yourself, only God can.
The Psalmist understood this when he wrote:
"Let your hand rest on the man at your right hand, the son of man you have raised up for yourself.  Then we will not turn away from you; revive us, and we will call on your name.  Restore us, O LORD God Almighty; make your face shine upon us, that we may be saved." Psalms 80:17-19 (NIV)
Who is this Man at your right hand, the Son of Man you have raised up for yourself - it is Jesus!
Martin Luther knew that when he wrote in the second verse of the hymn, "A Mighty Fortress Is Our God":
"Did we in our own strength confide, our striving would be losing,
Were not the right Man on our side, the Man of God’s own choosing:
Dost ask who that may be? Christ Jesus, it is He;
Lord Sabaoth, His Name, from age to age the same,
And He must win the battle."
Jesus is the only one who can revive and restore you. Call out to Him and ask Jesus to do what only He can do.
By the way, Jesus is also the only One who can revive a friend or loved one and save them. And just like when someone's physical heart stops they need someone to get them to those who can revive them, God wants to use you to bring someone to Jesus so He can revive their spiritual heart.
