Seeing the Lord’s Salvation

Christ is the God Man who enters history to do his father's will. John tells us that Christ tabernacled among us. This means that Christ is God dwelling in the midst of his people in the flesh. If Christ is the tabernacle then why does Christ go to the temple? Why do Christ’s parents bring him to the temple? If Christ is the walking temple then why does Luke tell us about Christ in the temple? Is Luke contradicting or complimenting John's Gospel?
