Christians are called to be disciples.
A disciple is one who studies Jesus and follows him in obedience.
A disciple also is one who seeks to bear fruit. This is where abiding comes in.
“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)
I suggest that practicing the spiritual disciplines is a key to abiding in Jesus.
The disciplines, when practiced, help us rest in Him, Be changed by Him and bear fruit that gives Him glory.
