As with the wind which we cannot see but can witness its effect, similarly we cannot see God but we can bear witness to Him. (John 3:8 "The wind blows wherever it pleases. You hear its sound, but you cannot tell where it comes from or where it is going. So it is with everyone born of the Spirit.” )
God desires us to have a relationship with Him, getting to know Him, despite us not being able to physically see Him for now. (John 17:3 "Now this is eternal life: that they know you, the only true God, and Jesus Christ, whom you have sent".)
