The call of God creates sight in us. It's the work of God in our hearts to awaken us before his word.
John PiperThe deepest longing of the human heart is to know and enjoy the glory of God. We were made for this.
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 Piper
