My dad used to stand at the fence row, purse his lips, and let out a high-pitched, very shrill whistle. There was no mistaking that sound, and it could be heard for a country mile—at least by four little people last-named Potter. We knew what that sound meant—Dad was calling. There was only one acceptable response to that whistle: come home. And we did. Without question. Without delay. And without thinking twice.

God stands at the heart’s door and knocks—He calls out with a desire to be heard by His children. For some it is a call to initial belief. For others—those who already know Christ—it is more likely a call to return to the fold, to come home. To this call there is only one acceptable response: come home. Have you heard the calling of God lately? Is it, for you, a call to repentance? Or perhaps it is a call to serve others in the name of Christ. Our encouragement today is to join with Isaiah in His answer to God’s calling with readiness to follow that calling voice. Without question. Without delay. And without thinking twice.

“I heard the voice of the Lord saying: ‘Who should I send? Who will go for Us.’ I said: ‘Here I am. Send me.’” –The Prophet Isaiah (Isaiah 6:8)
