Hebrews 5:14 (ESV): 14 But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil.
In Hebrews 4, the writer spoke of the Sabbath rest that is available for those who believe in Jesus. By illustration, the rebellious Israelites in the desert failed to enter that rest.
The end of Hebrews 4 into Hebrews 5 transitions, talking of Jesus as our great high priest who is able to sympathize with our weaknesses, yet did not commit sin and thus can intercede for us with the Father.
At the end of Hebrews 5, the writer again pauses to scold his readers, saying that they should to be able to teach such truths by that time, but instead needed to receive the foundational teachings again.
If we are to grow spiritually, we must apply ourselves to study and apply God’s Word. There is a real danger for the believer of accepting God’s truth, but failing to put it into action, becoming ever more knowledgeable of truth, but denying the truth by their life.
Heavenly Father, may I always continue to grow in both understanding and application of your truth. Amen.
