Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the lust of the flesh, the lust of the eyes, and the pride of life—is not of the Father but is of the world. - 1 John 2:15-16

Set your mind on things above, not on things on the earth. For you died, and your life is hidden with Christ in God. - Colossians 3:2-3

For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ. - 2 Corinthians 10:4-5

Commit your works to the Lord,
And your thoughts will be established. - Proverbs 16:3

Wisdom is in the sight of him who has understanding,
But the eyes of a fool are on the ends of the earth. - Proverbs 17:24

I will set nothing wicked before my eyes;
I hate the work of those who fall away;
It shall not cling to me. - Psalm 101:3

Keep your heart with all diligence,
For out of it spring the issues of life. - Proverbs 4:23

Let the words of my mouth and the meditation of my heart
Be acceptable in Your sight,
O Lord, my strength and my Redeemer. - Psalm 19:14
