"The steadfast of mind You will keep in perfect peace, Because he trusts in You.” Isaiah 26:3
Some types of anchors are designed with sturdy hooks to dig into a sea bottom, or latch on to a big rock. They halt a boat’s drag, caused by wind and waves. The soul needs to be anchored. Paul wrote that we are “tossed” about by winds and waves of differing beliefs (Ephesians 4:14). James describes the doubt that sometimes causes us to be driven on the surf of unbelief, and carried along with whatever wind may be blowing (James 1:6). But faith in God anchors the soul, stops the drift and drag, enabling us to rest, even in stormy seas.
