Falling short is often not a result of doubting God's word but instead in doubting his vessel. God plants the seed and in the same season hand picks the servant he sees fit to toil it as well. However, through are own understanding, we choose to trust only in the promise of God and not in his ability to secure the appropriate vessel to bring it to fruition. Just as the Jewish people did with Jesus we uphold one part of the promise and arrogantly reject the rest as if God is only capable of the "what" and not the "how". In this season of our lives, let us be reminded of Isiah 46:10 which states "Only I can tell you the future before it even happens. Everything I plan will come to pass, for I do whatever I wish."
Let us meditate on this word and others below and see how they manifest within our lives and improve our perspectives, expectations, as well as our accompanied behaviors.
