Stirring the pot means to cause trouble and confusion. Some people stir up controversies and arguments, which result in divisions. Peter calls the disciples to stir up the sincere mind. (II Peter 3:1) There are people with pure minds, but they are passive. So, only Peter encourages in his letter to stir up the pure minds.
Impure minds: When a mind is not renewed, it is impure. (Romans 12:2) Stirring up such minds that are corrupted or saturated by sinful thoughts would result in disaster and destruction.
Pure mind: The Greek word used by Peter means something which is pure when examined in bright sunlight. That means the mind that is without guile, or deception, but fully devoted to truth. In fact, pure minds would think 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. (Philippians 4:8)
Stirring up: It contrasts with passively consuming the information. Stirring up your mind stimulates wholesome thinking. First, Believers ought to meditate on Scripture, setting aside any emotional or sentimental or tradition-driven arguments, and rely on the Holy Spirit to enlighten the mind. Second, the truth learned by meditation should become the worldview or foundation for all decisions in life. Third, it also calls to remember the way the Lord led each one of them. (Deuteronomy 8:2) Remember the lives of the leaders, their outcome, and their fruitful lives, and imitate their faith. (Hebrews 13:7) Fourth, to re-engage in the spiritual activities that have been neglected from being less fervent for the Lord. Lack of spiritual disciplines of prayer, fasting, fellowship, and meditating on the Scripture. Losing the first love that results in disengagement with other believers has to be reversed. Five, receiving a fresh vision that will direct the future life. Six, Realignment of life with the priorities of the Kingdom of God, and the Values of His Kingdom, which is righteousness. (Matthew 6:33) Seven, rejoicing in the Lord always, and moving forward doing His will.
