"Who is sufficient for these things?" ~ 2 Corinthians 2:16b
No one is.
Not in our own strength, creativity, or self-awareness.
Not with our own resources.
Not according to God's terms and conditions.
Not within the limits of our own emotional capacity or energy.
We need Someone outside of us to provide the full sufficiency and effectiveness for spreading the Gospel aroma of Jesus Christ to everyone in the world.
All it takes on our part is to say to God, "Here am I. Send me."
