We have this as a sure and steadfast anchor of the soul, a hope that enters into the inner place behind the curtain, where Jesus has gone as a forerunner on our behalf, having become a high priest forever after the order of Melchizedek. (Heb 6:19–20)
You would think that just dropping the anchor on a boat would be all you would need to do to stop your boat drifting away. However, in Alaska, the difference between low tide and high tide can be up to 27 ft. Dropping anchor at low tide might cause the rising tide to sink your boat as the rising tide exceeds the length of your anchor chain. So, some folks have an anchor system where the anchor is attached to a buoy, with a rope attached to the beach. A boat ties up to the buoy and is safe from changing tides, and from being pushed onto the rocks.
Having faith in Jesus is a sure anchor of our faith. However, that faith often comes with traditions, dogmas, and beliefs, many of which may not be found in the Bible. When change comes your way, it can be all the extras that will sink your faith. The gospel will never change, but our understanding of scripture, God moving in new ways and doing new things is always possible. Our understanding should be flexible as we grow as a Christian. If your anchor has some flexibility, you will be able to move with the tides.
As Robert Critchley wrote:
My hope is built on nothing less
Than Jesus’ blood and righteousness
I dare not trust the sweetest frame
But wholly lean on Jesus name
On Christ the solid rock I stand
All other ground is sinking sand
All other ground is sinking sand
