When you are in the battle over your thoughts read:
Psalm 19:14 (NKJV)
14Let the words of my mouth and the meditation of my heart Be acceptable in Your sight, O Lord, my strength and my Redeemer.
Psalm 1:1–3 (NKJV)
1Blessed is the man Who walks not in the counsel of the ungodly, Nor stands in the path of sinners, Nor sits in the seat of the scornful;
2But his delight is in the law of the Lord, And in His law he meditates day and night.
3He shall be like a tree Planted by the rivers of water, That brings forth its fruit in its season, Whose leaf also shall not wither; And whatever he does shall prosper.
1 Peter 1:13 (HCSB)
13Therefore, with your minds ready for action, be serious and set your hope completely on the grace to be brought to you at the revelation of Jesus Christ.
Philippians 4:8–9 (NKJV)
8Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy—meditate on these things.
9The things which you learned and received and heard and saw in me, these do, and the God of peace will be with you.
1 Timothy 2:5 (NKJV)
5For there is one God and one Mediator between God and men, the Man Christ Jesus,
Hebrews 4:14–16 (AMP)
14Inasmuch then as we have a great High Priest Who has [already] ascended and passed through the heavens, Jesus the Son of God, let us hold fast our confession [of faith in Him].
15For we do not have a High Priest Who is unable to understand and sympathize and have a shared feeling with our weaknesses and infirmities and liability to the assaults of temptation, but One Who has been tempted in every respect as we are, yet without sinning.
16Let us then fearlessly and confidently and boldly draw near to the throne of grace (the throne of God’s unmerited favor to us sinners), that we may receive mercy [for our failures] and find grace to help in good time for every need [appropriate help and well-timed help, coming just when we need it].
