He will raise a signal for nations far away, and whistle for them from the ends of the earth; and behold, quickly, speedily they come! (Isaiah 5:26 ESV)
Whistle
We do not let our dog out without a leash. He is a curious beast, and would follow his nose wherever it goes. And I have not trained him to come back when I call. My poor dog.
Training a dog to come when called is hard, but not impossible, work. But when I consider why I have not made the effort, I must admit something. I have not taken the time to teach him to come when I call, yell, or whistle, because I really do not love him that much.
But God whistles for His people to come. That whistle goes out in His Word, through His Spirit, through His creation, and through His people. God whistles both loudly and subtly. God whistles both to the well-known and the hidden. God whistles to everyone that He desires to come to Him. And because He loves His people, He whistles a lot, without stopping.
God loves His people. Listen, and come quickly.
