Jesus is the only Son of God, eternally begotten of the Father, God from God, Light from Light, true God from true God, begotten not made, of one being with the Father.  Through him all things were made.

Jesus Christ, born about 2000 years ago, was God's son

He is also the second "person" of the one God, the third being the Holy Spirit

That is, he is the Son of the Father and yet is also himself God

Despite Jesus being born 2000 years ago, the Son of God existed before the creation of the world.

For us and for our salvation he came down from heaven:  by the power of the Holy Spirit he became incarnate from the Virgin Mary, and was made man.

Because of God's love for us he gave up being The Almighty and became a man in the person of God's Son, Jesus of Nazareth.

Jesus is therefore both God and human.

It sounds like a contradiction in terms to be both, like being both a square and a triangle.  It is really more like being both a square and red.

Jesus was not just a "meat puppet," God wearing a human body.  He was God become human, completely.

For our sake he was crucified under Pontius Pilate; he suffered death and was buried.

God gave himself up for us completely.

God did not just offer us a helping hand or a little boost so we could make it on our own.

Remember, Jesus was not a "meat puppet."  God the Son died on the cross.  It was not just an act.

On the third day he rose again in accordance with the Scriptures; he ascended into heaven and is seated at the right hand of the Father.  He will come again to judge the living and the dead, and his kingdom will have no end.

For as in Adam, all die, so also in Christ shall all be made alive.  Alleluia!

The life of God is eternal, not simply unending but unbounded by time.  In the death and resurrection of Jesus that life was given for us and given to us.  We, like Jesus the God-man, are given the chance to be made "God-persons," sharers in the eternal life of God.

The life of God is a gift, a free gift, with no strings attached.  We could not earn it if we tried.  All that is left for us to do is say "Yes please!" and "Thank you!"

We say "Yes, please!" in Baptism, the ceremony in which we ritually take part in the death and resurrection of Jesus Christ.

We say "Thank you!" by doing what we think pleases God.  We do not, for example, help the poor because we are "trying to get into heaven."  We help the poor because it pleases God.  It is very much the same as being in love.  We bring home flowers to please our loved one, not so that they will love us more.  Because God gave his life to us, out of love we respond by giving our lives to God.
