The realness of God is what makes people different. Introduce God as a person, not a religion. Be Holy Spirit filled and bring all life’s areas into His presence and care.
The turning point is the realization that He is alive and we are filled with the Holy Spirit and surrounded in His Presence. This truth gives us a glorious awareness of God.
If you’re troubled with doubts, and I suppose everyone is at sometime or other in his or her life, get into God’s Word, and read the promises that He’s made and the prophecies that have been fulfilled.
Without faith, you cannot please God fully and then results and His plans can be hindered. It hurts God when we reject Him or don’t believe He can do something. He can and He will. Just trust Him.
