Hopefully making theology simpler to understand! (2 Corinthians 1:12)

Abide in me, and I in you. As the branch cannot bear fruit by itself, unless it abides in the vine, neither can you, unless you abide in me.
John 15:4, ESV

All that we do is tainted by sin, like a plant in a planter without good water or nutrients barely growing. We need the life-giving water of the Holy Spirit to truly do good works to bring glory to God.
