The mind is the control tower of life. Decisions determine actions, which in turn affect the immediate and distant future. The person each of us will be 20 years from now is impacted by how we think today. If we want our future self to be pleasing to the Lord, then we must begin at once to program our mind with godly thoughts.
In Romans 12:2 and Ephesians 4:23, Paul tells believers to reject worldly thinking and renew the mind. We have been given the capacity to think as Jesus does—if we submit to the transforming work of the Holy Spirit. The believer should seek the things of God as an act of submission. This means opening our minds only to biblically sound attitudes and philosophies. It’s important that we protect ourselves from the world’s self-serving mindset, because we are to be God’s servants.
A second way to submit is by sifting our thoughts through the Word and will of God. This is a practical step that allows us to identify wrong thinking. We must consider whether an attitude or line of reasoning is pleasing to the Lord and useful for making us into the person He has called us to be. Then, when a thought is unscriptural, we can choose to reject it (2 Cor. 10:5).
Of course, the only way to know if a thought pleases the Lord is to read and meditate upon His Word. In the Bible, God provides examples of righteous living and thinking, and He offers guidance for choosing such patterns. Scripture is the instruction manual for our control tower.
