From The Jesus I Never Knew, by Philip Yancey.
"God is not a Nazi," said Thomas Merton. Indeed God is not. the Master of the universe would become its victim, powerless before a squad of soldiers in a garden. God made himself weak for one purpose: to let human beings choose freely for themselves what to do with him."
Although power can force obedience, only love can summon a response of love, which is the one thing God wants from us and the reason he created us. "I, when I am lifted up from the earth, will draw all men to myself." God's nature is self-giving; he bases his appeal on sacrificial love.
I remember the night I gave my life to Jesus. I was at an evangelistic meeting. I found all the facts from the Bible interesting but every night when they gave a call for people to come forward I didn't feel an urge to do it. Then one night the preacher spoke on Jesus' love. I even remember now the picture of Jesus they put on the screen. I felt in awe, I felt moved, I felt a presence overshadow me. I stood up as if in a dream and walked up to the stage and gave my life to God. His love was the one thing that drew me.
