Hebrews 13:8 (ESV) … “Jesus Christ is the same yesterday and today and forever.”
Though times and leaders change, Jesus Christ does not. Christ is the same all the time. He served faithfully yesterday (dying on the cross to make atonement for our sins; see 2:17–18). He serves faithfully today (interceding for us at the right hand of God; see 4:14–16; 7:25). He will remain faithful forever. Because of what he has done in the past and what he does in the present, he is sufficient for any need any believer will ever have. (See also 1:12.)
Human leaders have much to teach us and we can learn much from emulating them (13:7), but we must keep our eyes on Christ, our ultimate leader. Unlike any human leaders, he will never change. Christ has been and will be the same forever. In a changing world we can trust our unchanging Lord.
