Why should anyone of us settle for serving ourselves?
God gives us all things so richly. His grace is a gift which brings blessings of all kinds in its wake.
"He who gave us His own Son, will He not freely give us all things with Him?" (Romans 8: 32)
What point is there to fighting and grabbing when the Spirit of God teaches us that all things are freely given to us through Christ (1 Corinthians 2: 12)
For this reason, why should not think too highly of ourselves, because we do not need to.
