You were made to be filled with his spirit, to display the preferences of his applications, and to draw power from His external source. You were designed for Him to reach and speak to others through you, and to convey a message through text and through sound. You're given a voice like a speaker, hearing like a microphone, and seeing like a camera. You have a light to shine and see in the dark, and a face that seeks his face, so you can be used for his purpose. God made us, and paid for us. He is not only the designer, but also the purchaser, and your phone exists to reflect His relationship to you. The Bible mentions man as a device, instrument, or tool of God in several verses, including: Jeremiah 51:20 - "Thou art my battle axe and weapons of war: for with thee will I break in pieces the nations, and with thee will I destroy kingdoms;" Romans 9:21-23 - Comparing humans to clay, God is the potter shaping vessels for honor or dishonor. Timothy 2:21 - Believers are vessels unto honor, sanctified and meet for the master's use. Isaiah 10:5 - Assyria is referred to as a rod of God's anger. We are also modeled by trumpets, remote controls, kitchen knifes, computer mouses, conductor batons, and more. These analogies and verses highlight God's sovereignty and humanity's role as vessels in His hand, and finding these models in our own lives, is the voice of God speaking to us through His creation.
