The conviction that comes from the Holy Spirit results in power to overcome sin, resist temptations. We have the faith of Jesus and we testify Him having victory because we chose to receive the power of the Holy Spirit to crucify the flesh, having died, and now resurrect and remain resurrected with Christ overcoming as He overcame, enduring unto the end—we testify of His power to deliver us from sin.
