Spiritual immaturity is a problem because God commands Christians to grow (2 Pet. 3:18), but also because true spiritual life inherently includes growth (2 Cor. 3:18). More importantly, however, spiritual immaturity could be an indication that we don't actually belong to Christ at all. For all these reasons, it is crucial for those who claim to be Christians that they be clear on the essentials of Christian truth and living, and that they be growing from that foundation into greater degrees of Christlikeness.

The warning passage of Hebrews 6 has long been one of the most sobering passages in all of Scripture because of its straightforward warning: if you fall away from the faith, you cannot be saved and there is nothing left for you but hell. What does it mean to fall away, and how do I know if I am a candidate? Thankfully, the Word of God is not silent about this, but has given several points by which to examine ourselves to see if we are, in fact, in the faith.
