No matter how much you can speak to a person about Christ, if the spirit is not involved, you are waisting your time. I used to enjoy criticizing Christian until one day God decided himself to end it. John 8:9 Then those who heard it, being convicted by their conscience, went out one by one, beginning with the oldest even to the last. And Jesus was left alone, and the woman standing in the midst.
Sin is spiritual therefore requires spiritual intervention. Sometimes you hear people commenting about spiritual things when they are not spiritual themselves and act like they know it all. Time will come when Jesus will take control of their lives, one just hope it’s not too late for some. John 8:12 Then Jesus spoke to them again, saying, “I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life.”
Saul thought he’s got everything under control not knowing that he will hit a forced stop in his life. When all you think you knew becomes a lie. Acts 9:3-4 As he journeyed he came near Damascus, and suddenly a light shone around him from heaven. Then he fell to the ground, and heard a voice saying to him, “Saul, Saul, why are you persecuting Me?”
