"Do not be conformed to this world, but be transformed by the renewal of your mind…” Excerpted from Romans 12:2 (ESV).
The verse continues “that by testing you may discern what is the will of God, what is good and acceptable and perfect.”
Christians don’t automatically get a new mind when we get saved. Our old mind, however, has to be transformed. This verse explains the only way our old minds can be transformed is by renewing it with God’s word.
The result of mind renewal is that our discernment capacity is increased and refined.
We hold our minds up to the probing light of scripture and wherever there are any differences we submit to God’s word. This produces new minds.
