Just beware. Raising a hand and saying a prayer does not save your soul. It's the believing on Jesus personally as your Savior in changing(repenting) what you used to believe and trust in, to solely trusting what Christ did on the Cross and resurrection was for you
Repenting means you stop trying to sin and you start trying to obey God's commandments. We are saved by grace through faith, but faith without works is dead (James 2:17)
