Mortar is used to hold building materials such as brick or stone together. It is composed of a thick mixture of water, sand, and cement. The water is used to hydrate the cement and hold the mix together.
There is an old song that Burt Bacharach and Hal David wrote, What the World Needs Now is Love, that came to my mind this morning. With all that is going on in our world, we can be used by God to hold people together. Not for peace in the world, but peace in hearts. True Love is a gift from God that is available for all who might receive it. (and there is no shortage from the maker). If we will let the power of God and the direction of the Holy Spirit work in us (the sand), We can make a difference. Will we take time to share this wonderful gift?
Col 3:14
And over all these virtues put on love, which binds them all together in perfect unity.
