The Bible has much to say about our minds and how we are to use our minds to know and worship the God of all wisdom and insight. Here are eight truths found in Scripture that ought to inform and shape our thoughts.
There is a battle for our thought life and we must engage this battle.
2 Corinthians 10:3–6
 For though we walk in the flesh, we are not waging war according to the flesh.  For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds.  We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ,  being ready to punish every disobedience, when your obedience is complete. (ESV)
 For I delight in the law of God, in my inner being,  but I see in my members another law waging war against the law of my mind and making me captive to the law of sin that dwells in my members. (ESV)
Our minds can be hardened and blinded.
2 Corinthians 3:14–16
 But their minds were hardened. For to this day, when they read the old covenant, that same veil remains unlifted, because only through Christ is it taken away.  Yes, to this day whenever Moses is read a veil lies over their hearts.  But when one turns to the Lord, the veil is removed. (ESV)
2 Corinthians 4:3–4
 And even if our gospel is veiled, it is veiled to those who are perishing.  In their case the god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God. (ESV)
Our minds need reforming from the default of this world.
 Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. (ESV)
Christians are given the mind of Christ and spiritual understanding
1 Corinthians 2:16
 “For who has understood the mind of the Lord so as to instruct him?” But we have the mind of Christ. (ESV)
 Then he opened their minds to understand the Scriptures, (ESV)
1 John 5:20
 And we know that the Son of God has come and has given us understanding, so that we may know him who is true; and we are in him who is true, in his Son Jesus Christ. He is the true God and eternal life. (ESV)
 Have this mind among yourselves, which is yours in Christ Jesus, (ESV)
Christians are to set their minds on the things of God.
 For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit.  For to set the mind on the flesh is death, but to set the mind on the Spirit is life and peace. (ESV)
 But turning and seeing his disciples, [Jesus] rebuked Peter and said, “Get behind me, Satan! For you are not setting your mind on the things of God, but on the things of man.” (ESV)
 Set your minds on things that are above, not on things that are on earth. (ESV)
Our worship to and love of God ought to include the use of our minds. (Worship is not merely emotional.)
1 Corinthians 14:15
 What am I to do? I will pray with my spirit, but I will pray with my mind also; I will sing praise with my spirit, but I will sing with my mind also. (ESV)
 And you shall love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength. (ESV)
There is an expectation that we grow in the area of our thought life.
1 Corinthians 14:20
 Brothers, do not be children in your thinking. Be infants in evil, but in your thinking be mature. (ESV)
There is a relationship between our thought life and our experience of God’s presence.
 do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.  And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.  Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things. (ESV)
 But this I call to mind,
and therefore I have hope:
 The steadfast love of the LORD never ceases;
his mercies never come to an end;
 they are new every morning;
great is your faithfulness. (ESV)
 You keep him in perfect peace
whose mind is stayed on you,
because he trusts in you.
 Trust in the LORD forever,
for the LORD GOD is an everlasting rock. (ESV)
