I love this thought or rather this truth! The Lord sustains me and He keeps me in all my ways! According to the Strong's Concordance the word sustained comes from a primitive root meaning to prop (both literally or figuratively): reflex. it means to lean upon or to take hold of (in a favorable or unfavorable sense.) What that means is that as His people we can rest, assured in the knowledge that He has our back!
We can lean on Him as He takes hold of all the things we deal with on a daily basis. It is easy to understand that we can look to Him when we are facing a difficult situation but how often do we acknowledge that He is the one we look to for everything else as well. I think that it is an all to often event for His people to take His "sustaining touch" on our day to day for granted! I think that all to often the thought of our heart is ... I've got this and we forget to even acknowledge that He holds us up in all that we do!
He has a good hold of us and He sustains us as promised ... "See, I have inscribed you on the palms of My hands; Your walls are continually before Me." Isaiah 49:16
