Supporting, anyway you look at this word it means to help in some way or fashion, from being a foundation to just a little nudge of help. When Paul was teaching in Rome he had these words to say...Definition of support (verb)

These verses are talking about the Gentiles (us) being allowed into the family of God. There were branches broken off because of unbelief, those in Israel who did not believe that Jesus is the Son of God. The wild olive tree were the Gentiles who were believing in faith. They had not been witness to the events but believed anyway. Paul was reminding them that the root, the foundation was Jesus and that they had nothing to do with their salvation, He did. They could still be cutoff if they did not live in His goodness. That doesn't mean that they no longer would have salvation but that they would not have or feel the support of the root any longer.For if the first fruit is holy, the lump is also holy; and if the root is holy, so are the branches. You will say then, “Branches were broken off that I might be grafted in.”
God does not need us to do anything here on the earth. He does not need our support. He is our support. Yet, I think he wants us to be willing to "support" His family, to be willing to be the tool He uses to provide the support He gives. That may be in the form of just a prayer, a kind word, maybe buying groceries for a needy person, or just giving a hug. Whatever way you help God support someone, it helps to deepen your graft into the tree, where the root can support you more.
I hope this makes sense... I really didn't know where to go with this word, because it is one of those obvious words... There is a negative side to supporting someone but I didn't want to go there.
Thanks for Reading. God Bless You all!
