Often Hebrews 6:4-6 is a troubling passage for believers. The writer of Hebrews is exhorting his audience to mature in the faith. He points out that they are still living on the milk of the gospel when they should have matured in the solid food of the Word of God. As we mature, our powers of discernment will be honed and we will be able to discern good from evil and walk the path of righteousness. God's desire for all of us is to go on to maturity - to grow in the grace of God.
