Often when someone is really studying the Bible in depth for the first time, they realize what they were taught or led to believe about Christianity and the Bible is wrong. Sometimes people who had already been baptized into a church or denomination wonder whether or not their baptism is valid. If you're in this situation, here are a few questions to consider:
Did I have a repentant attitude when I was baptized?
Was I completely immersed under water during the baptism?
Was there a laying on of hands after my baptism and a prayer asking for my receipt of God's Spirit?
Have I developed solid biblical understanding after baptism?
Do I have a healthy and effective prayer life?
Am I making progress in overcoming sins and human nature?
Positive answers to these questions mean God's Spirit is likely working with or in you. It's a good idea to talk to a pastor about these things and whether or not you should be re-baptized. You can find the contact information for your nearest United Church of God pastor here.
