The ultimate difference between God's wisdom and man's wisdom is how they relate to the glory of God's grace in Christ crucified. God's wisdom makes the glory of God's grace our supreme treasure. But man's wisdom delights in seeing himself as resourceful, self-sufficient, self determining, and not utterly dependent on God's free grace.
John PiperDon't wait for a feeling or love in order to share Christ with a stranger. You already love your heavenly Father, and you know that this stranger is created by Him, but separated from Him... so take those first steps in evangelism because you love God. It is not primarily out of compassion for humanity that we share our faith or pray for the lost; it is first of all, love for God.
John PiperDoes Christ get a good reputation because of the way we live? Is the excellence of Christ displayed in our lives? That should matter to us, not whether we ourselves are praised.
