We Love God!

God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)

If marrying an unbeliever is outside of God's will, then dating one must also be off limits. You cannot date someone who is spiritually dead and simultaneously please Christ (Rick Holland).

The root that nourishes fruitful hearing is the root of faith. Hearing begets faith and faith begets better hearing. Trusting in the truth you already have is the best way to prepare yourself to receive more. So when you pray and meditate and turn off the TV, consciously fix your heart on the promises of God and trust him Saturday night and Sunday morning.
John Piper
