All things were made and came into existence through Him; and without Him was not even one thing made that has come into being. John 1:3
Jesus made everything, and He controls everything. There is nothing that your Lord, your Vine, your Head, your Savior, your Deliverer, and your Protector is not in charge of.
Yet for us there is [only] one God, the Father, Who is the Source of all things and for Whom we [have life], and one Lord, Jesus Christ, through and by Whom are all things and through and by Whom we [ourselves exist]. 1 Corinthians 8:6
For it was in Him that all things were created, in heaven and on earth, things seen and things unseen, whether thrones, dominions, rulers, or authorities; all things were created and exist through Him [by His service, intervention] and in and for Him. And He Himself existed before all things, and in Him all things consist (cohere, are held together). Colossians 1:16-17
What this means is that nothing is taking place in your life that Jesus is not in control of. This is why all things are working for your good.
For we are God’s [own] handiwork (His workmanship), recreated in Christ Jesus, [born anew] that we may do those good works which God predestined (planned beforehand) for us [taking paths which He prepared ahead of time], that we should walk in them [living the good life which He prearranged and made ready for us to live]. Ephesians 2:10
We are assured and know that [God being a partner in their labor] all things work together and are [fitting into a plan] for good to and for those who love God and are called according to [His] design and purpose. Romans 8:28
