At the start of Jesus’ 3-year project of discipling his 12 chosen men, we learn that “…they were astonished at His teaching, for He taught them as one having authority, and not as the scribes.” Mark 1:22
In times of relative peace and quiet, the virtue of courage is often unseen and little spoken of. But when the pressure is on; when the conflict of good and evil is raised for all to see; when the dangers and threats of evildoers are brazen and menacing, then courage arises in those who are empowered with personal knowledge and experience.
Jesus communicated confidence with authority, not just because he had personal conviction. He had deep intimate knowledge of the truth that He spoke. He dwelt in the shelter of the Most High. He displayed the epitome of courage because He was in tune with the Father and only did what He saw Him do.
