Yes, our minds and the decisions we make can lead us astray. It is most interesting to read what Jesus said to Peter.
According to what Jesus declared about Peter, a Christian can be a tool of the devil, if he is not closely walking the Spirit-controlled life. There are times when we do not have 'the mind of God' but are just voicing a humanistic opinion.
Therefore, Paul challenges us in this scripture:
You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires; to be made new in the attitude of your minds; and to put on the new self, created to be like God in true righterousness and holiness.
[Ephesians 4:22-24]To avoid being deceived and speaking out ungodly statements, we mut 'put on' God's replacement programme every day:
..and have put on the new self, which is being renewed in knowledge in the image of its Creator. [Colossians 3:10]
Put off the old nature and put on the new nature, and you will have the mind of Christ.
Don't let the lies of Enemy propaganda penetrate your mind.
