When I had a project that I wanted rock-solid, one that would last, I chose concrete. It’s kid-proof, and it isn’t going anywhere. I’ve thought of concrete similar to 1 Corinthians 15:58. “Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.” 

Steadfast and unmovable were what I thought of regarding concrete, but I’ve since modified that opinion. Years ago there was a concrete patio outside the backdoor of a house we lived in. Recently, I had the opportunity to get a good look at that patio after 20 years. 

Much of the patio was still intact, but there was a large crack that separated it into two big slabs. The side closest to the house had sunk over a foot. What seemed stedfast, was still very firm, but it had moved – in fact to the point of not being usable. The patio concrete moved because the ground it was resting on next to the foundation sunk. If the patio had been “pinned” to the foundation, it would not have moved when the ground moved. 

That is what we need if we are to be steadfast and unmovable. Even if we are solid in our beliefs, we must be pinned/attached to the Lord Jesus, our God, our rock, Who is unchangeable. “Be thou my strong habitation, whereunto I may continually resort: thou hast given commandment to save me; for thou art my rock and my fortress” (Psalms 71:3). We will be pulled down by the world around us. It might look firm, but it’s a slippery slope, and we will slide with it. 

“The LORD is my rock, and my fortress, and my deliverer; my God, my strength, in whom I will trust; my buckler, and the horn of my salvation, and my high tower” (Psalms 18:2).
