No one can have a purpose in reality unless his heart is fixed with confidence toward God. If you understand the importance of God’s purpose and the great principles involved, then you know what it means to have your mind fixed on things above (Colossians 3:1-2).
Though we need to be occupied with the job, our life is not derived from a job. Instead, it comes from the things above that God has made to dwell in me.
If we set our minds on things above, then no one can offend us. No one can make us insecure. We don’t need to react in any situation. Our flesh doesn’t have to be supported. People without Christ may need to do these things, but we do not because we are in God’s purpose, operating by God’s purpose, and working for God’s purpose.
