“For though by this time you ought to be teachers, you need someone to teach you again the first principles of the oracles of God; and you have come to need milk and not solid food” (Hebrews 5:12).
A significant and unique trait of humanity is an innate sense of “ought”. Lesser forms of God’s creation are governed solely by instinct. They have no moral or ethical codes.
To think in terms of duty, obligation, or moral responsibility is evidence of divine creation and is thus, a powerful proof for the existence of God. Not only can we find proof of God’s existence in the heavens and earth around us (Romans 1:20), the sense of moral obligation within us subtly, yet clearly, demonstrates it also.
One of the spiritual duties every Christian has is to grow in Christ and become knowledgeable and mature enough to teach others.
Spiritual growth is not a suggestion; it is an obligation.
