Prune yourself

'So put to death the sinful, earthly things hidden within you. Have nothing to do with sexual immorality, impurity, lust, and evil desires. Don't be greedy, for a greedy person is an idolater, worshiping the things of this world.'  — Colossians 3:5

We should consider ourselves dead and unresponsive to sexual immorality, impurity, lust, evil desires, and greed. Just like diseased limbs of a tree, these practices must be cut off before they destroy us- (Tyndale) 

~Grass and wild plants grow spontaneously, and flowering and fruit trees are grown by planting, watering, fertilizing and pruning. It is the same with carnal desires and good thoughts.~
