All the money needed to send and support an army of self-sacrificing, joy-spreading ambassadors is already in the church.
John PiperLove is the overflow of joy in God! It is not duty for duty's sake, or right for right's sake. It is not a resolute abandoning of one's own good with a view solely to the good of the other person. It is first a deeply satisfying experience of the fullness of God's grace, and then a doubly satisfying experience of sharing that grace with another person.
John PiperWe ought not speak too long about God with our minds before we turn and speak to God from our heart. We must stir a lot of prayer into the stew of our theology.
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.
