The Godhead contains God the Father, God the Son, and God the Holy Spirit. They are the ultimate best thing ever. I love them all. God is my heavenly Father that created this universe, the Son of God who saved us by dying on the cross is Jesus, and God the Holy Spirit is the guide. Don't forget, that the Spirit is what blesses us with the gift of speaking in another tongue. That gift is important, because that's just one way that Satan cannot or have the ability to understand what we're saying. Another thing, another experience that pertains to this is that you can be slain. While you're slain, God blesses you. God has the power to do all things. He can heal the sick, raise the dead, provide us with our needs, and perform miracles. We have to remember the book that helps us live out a godly life. In other words, the Bible teaches us to live under God's will.
To become a Christian, we must admit to God that we have sinned and give our whole heart to him. He uses salvation and grace to forgive our sins. As soon as that is done, we begin our walk with him until it is our time to go to heaven.
