While the heavens declare the glory of God, we are made in His image. We can see Him by looking into others around us. In Biblical context, that understanding pre-exists the salvation of the individual. This is to say that we can see the image of God in every person.
God walked into my office today in the person of a couple of people. Each showed me His love, creativity, ingenuity and concern. God's amazing. He keeps me focused on Him if I keep my eyes open for Him.
Look up. look out. Look for Him.
1 John 2:5 (MSG)
5 But the one who keeps God's word is the person in whom we see God's mature love. This is the only way to be sure we're in God.
