Disbelieving the gospel of the water and Spirit is not only Rejecting the Word of baptism of Jesus, saying I do not believe in Jesus` baptism, but, you can begin to disbelief the gospel truth of the Water and the Spirit Even as you believe in the baptism of Jesus, His death and His resurrection when you begin to condemn others due to their insufficiencies, saying; how can that brother or sister do that, how can he or she say such words as if she is not born again of the Water and the Spirit. But believe me, you, such a life is not a life of faith before God. If God took away all our sins through His baptism, death and resurrection and accomplished our salvation once and for all and He remembers not nor count our sins anymore. Then who are you to begin to count other brethrens sins, busy pointing out their shortcomings, We must be people who walk in forgiveness day by day as we live in this world for the sake of other souls.
For the Gospel is always and only about forgiveness.
