If you're living in this world and believe the only things that exist are the things you can see with your eyes, you're selling yourself short and selling God short. Jesus expressed that while you can't see the Spirit - you can see the results of the Spirit and He compared that with the wind. You can't see the wind but you can certainly see the results of the wind!
Listen to this excellent sermon by Gary Wilemon as he discusses from God's word the unseen things and gives us examples of those individuals who could see the unseen!
