Jesus Christ is the Way, the Truth and the Life. We follow Him by preaching His message, caring for His disciples and serving others as He served.
"A man of many companions may come to ruin, but there is a friend who sticks closer than a brother" (Proverbs 18:24, New International Version).
True friends are indispensable, and the Bible has volumes to say on the subject—including how to know when you've found one and how to be one yourself.
