Be rooted and built up in Christ Jesus
“Therefore, as you received Christ Jesus the Lord, so walk in him, rooted and built up in him and established in the faith, just as you were taught, abounding in thanksgiving.” (Col. 2:6-7 ESV)
Rooted and grounded in love
“That according to the riches of his glory he may grant you to be strengthened with power through his Spirit in your inner being, so that Christ may dwell in your hearts through faith—that you, being rooted and grounded in love, may have strength to comprehend with all the saints what is the breadth and length and height and depth, and to know the love of Christ that surpasses knowledge, that you may be filled with all the fullness of God.” (Eph. 3:16-19 ESV)
With no root they withered away
“Yet he has no root in himself, but endures for a while, and when tribulation or persecution arises on account of the word, immediately he falls away.” (Matt. 13:21 ESV)
“But when the sun rose they were scorched. And since they had no root, they withered away.” (Matt. 13:6 ESV)
Jesus is the root
“I, Jesus, have sent my angel to testify to you about these things for the churches. I am the root and the descendant of David, the bright morning star.” (Rev. 22:16 ESV)
