Matthew 7:18
A healthy tree cannot produce bad fruit and neither can a diseased tree produce wholesome fruit.
1 John 3:9-10
No one who has been [spiritually] conceived [and eventually born] by God continues to live a sinful life, because God's seed [i.e., His word, See Luke 8:11] continues to live in his heart, so he cannot [continue a life of] sin, because he has been conceived by God.
Galatians 5:17
For what your body wants is in conflict with what the Holy Spirit wants [for you], and what the Holy Spirit wants conflicts with what your body wants, for these [two desires] are contrary to one another, so that you do not [always] do what you [really] want to.
