The only thing required is our faith in God. Nothing else is required but to trust Him. As you can see faith is not something mystical. You do not wake up one morning and discover suddenly you have faith. It takes the word of God.
Scripture is the living Word of God.
God will be like a stranger to you. He will be like an inanimate object. How then can you trust a complete stranger for your salvation. For there is no distinction between Jew and Greek, for the same Lord over all is rich to all who call upon Him. Scripture is the key to life.
