The Lord Jesus was and is the greatest Teacher of God's ways.  He has never been one to simply talk.  In His earthly ministry and life, the Lord also taught us by example.  He placed the needs of others above His own interests — even to the point of going to the cross to pay for sins He never committed.

But the Lord's example of selflessness goes far beyond the cross.  Day in and day out, the Lord was showing the compassion of God for the needs and troubles we all face as human beings.  Jesus healed the sick and drove out demons, He raised the dead to life again, and He fed hungry people.  His heart was the very heart of God, and this was demonstrated in more ways, John says, than can be recorded. 

There is much more about Jesus that I have no room to mention here.  You can read about Him in the Bible.  The Old Testament book of Isaiah has much to say about Him, hundreds of years before Mary gave birth.  The Gospels of John, Matthew, Mark and Luke talk about His earthly ministry.  The Book of Acts tells about how the church on earth was formed.  The letters of Paul, Peter, John and others in the New Testament explain many things in wonderful detail.  And the Book of the Revelation of Jesus reveals Christ as He truly is, in all eternity: the Lamb of God who was slain before the ages, and the Eternal King who will reign over all things for ever.
