Dear friends, this is now my second letter to you. I have written both of them as reminders to stimulate you to wholesome thinking. 2 I want you to recall the words spoken in the past by the holy prophets and the command given by our Lord and Savior through your apostles.
2 Peter 3:1-2
So Peter is encouraging us to wholesome thinking.
Wholesome thinking comes when you’ve soak up so much of the world that you don’t have time to read the Word of God. Your thinking becomes distorted and askew. You begin to think as the world thinks. Your philosophy takes on worldly philosophy. Even your speech becomes affected and you are harsher than you should be. Your thinking about people and homelessness and refugees and orphans and marriage and the poor becomes distorted.
We return to wholesome thinking, of course, by getting into the Word of God. The Bible teaches us how to live so that our thinking can be wholesome, so that we may have compassion and mercy on people and their situations. The more we get into the Word of God, the more aligned with Biblical thinking we will be.
