There is no doubt in my mind, that Jesus did exist, there was a crucifixion, and more importantly, that he was resurrected. Jesus resurrected Lazarus, as well as many others. He is the Resurrection, the Truth, the Way, and the Life. We need to have our own spiritual resurrection. When we repent, we crucify the flesh.
Baptism is symbolic of burial.
The infilling of the Holy Spirit is the spiritual resurrection. God is praised only as high and as much as we praise Him. God is magnified only as much as we magnify His name. God is worshipped only as much as we worship His authority and power. God is glorified only as much as we let Him be glorified in us.
