I am a member of the One, Holy, Catholic and Apostolic Church by looking at unity, holiness, universality, and apostolicity SPIRITUALLY. Knowledge of God alone is no proof of salvation. Demons are fallen angels and they know God. They have seen God. There are many kinds of "FAITH". Many of them are "dead faith" and the other faith is true faith. True faith is that produces something and its living faith. "Oh," but he says "I believe, I believe," "Yeah," he says, "The devils believe and they tremble." Faith is not enough to believe unless that person's faith results in an act of commitment to Christ that results in a changed life that bears fruit. Jesus is the truth. True faith hears, believes, and actively responds from the heart. Faith comes as a result of the regenerating work of the Holy Spirit-He quickens our hearts to believe. Apart from the new birth, there can be no true faith.
