Contemporary English Version (CEV)
The cross is a simple device -- two boards, one vertical and one horizontal. Where they intersect, our Savior offered himself for the hope of humanity.
Our lives, too, should be lived at the intersection of the vertical and the horizontal. On the vertical, we orient ourselves to God, offering ourselves over and over again as a living sacrifice, pouring out praise and gratitude to God for all that God has done. Also, we focus on the horizontal, paying attention to the world around us, looking for ways to love and serve one another.
Without both, we lose something regarding the life of faith. We aren't balanced, and just as God calls us to himself, he equips us and sends us back out into the world, to love and to serve, to joyfully spread the Good News of Jesus Christ, who restores our hope by ascending the cross and showing us how to live, how to die, how to rise.
