I want to focus on the last part of this verse-- "Stay upon his God". The word "stay" means to "lean on, trust in, support, rest". We all need something to lean upon at some time or other. We all get tired and weary from running the race of faith that is set before us and need to be "propped up". The concern is not that we need to be propped up every once and a while or that we need something to lean upon and give us some support while we "catch our breath"; the concern is in "what" or "who" we lean upon.
There are so many things out there that look like "props". They look like they will hold us up and give us the support that we need until we can continue on. But that is not always the case. I remember the time I sat down on my porch swing to relax a moment. The next thing I knew the swing and I were both on the porch floor. It looked sturdy, it was made out of good strong material, the chains looked intact, they were metal, but it wasn't as dependable as it looked. The chain had rusted; therefore, it could not support my weight.
There is nothing that is man-made (fleshly) that we can lean upon to give us the support that we need. Like a house that is built on the sand. It looks pretty good, it looks solid, but there is no foundation under it. It will cave in and you will find yourself swept away by the very thing you are needing the rest from.
There is only one place that we can lean upon-- our God. There is only one place where we can get the rest that we need when we are feeling weary, afraid, pressured, faithless, confused and discouraged-- our God. When David and his men arrived at their home in Ziklag and discovered that the enemy had come and taken their families and stolen their belongings, this is what David did-- he leaned upon his God. His heart was broken, his men talked of stoning him, his family was gone, but he found a place where he could rest and lean upon for guidance and strength-- his God. The Lord propped him up by encouraging him, by giving him direction, by giving him strength. From that place of "rest and propping" David found what he needed to then go forth and destroy his enemy and save their families.
What is propping you up today? What are you leaning upon? Your own understanding, your education, your strength, your job, your government, your talents, a financial institution, other people, your spiritual leader? There is only one true prop that will never fail you or let you fall-- our God. You can lean upon Him. He is the foundation that was under the house that did not fall-- our God is the solid Rock.
Have a great day. There is only one prop that you can lean upon that will hold you up-- our God.
