Establishing roots  

Colossians 2:6-7 New Living Translation (NLT] 

6 And now, just as you accepted Christ Jesus as your Lord, you must continue to follow him. 7 Let your roots grow down into him, and let your lives be built on him. Then your faith will grow strong in the truth you were taught, and you will overflow with thankfulness. 

Colossians 2:13-15 New Living Translation (NLT) 

13 You were dead because of your sins and because your sinful nature was not yet cut away. Then God made you alive with Christ, for he forgave all our sins. 14 He canceled the record of the charges against us and took it away by nailing it to the cross. 15 In this way, he disarmed the spiritual rulers and authorities. He shamed them publicly by his victory over them on the cross. 

Ephesians 3:16-19 New Living Translation (NLT) 

16 I pray that from his glorious, unlimited resources he will empower you with inner strength through his Spirit. 17 Then Christ will make his home in your hearts as you trust in him. Your roots will grow down into God’s love and keep you strong. 18 And may you have the power to understand, as all God’s people should, how wide, how long, how high, and how deep his love is. 19 May you experience the love of Christ, though it is too great to understand fully. Then you will be made complete with all the fullness of life and power that comes from God.
