People join churches today with wrong expectations. They think church membership guarantees blessings and no burdens. Some think that God is just a heavenly cafeteria. And if it doesn't work out as they wish, they say, "Well, it's not paying off! I thought if I gave my heart to Jesus, then He would supply everything I want. And I'd have no more worries." People fall away because their expectations are not met. Let me tell you what real faith is. Real faith is not just receiving from God the things you want. Real faith is accepting from God the things He gives.
How are your spiritual eyeglasses? Are you looking at life with the eyes of the Lord? And trusting that He will provide, not necessarily what you want, but what you need?
