How can we preach Christ from all the Scriptures?  Tim Keller outlines how each of the major themes of the Bible gives an opportunity for pointing to our Lord and Saviour:-

1. Kingdom.  Jesus is the true King and he claims the whole world as his rightful domain.  In serving him we find perfect freedom.
2. Covenant.  We were made for relationships that are intimate yet binding.  God claims us for his own, so that he can be our God, and we his people.  On the cross, Jesus was faithful where Israel had been unfaithful.  He has brought us back from the separation that had come about by our breaking of the covenant.
3. Home and exile.  This world was made to be our home, a place of flourishing and fulfilment.  Our sin has exiled us, and the world no longer satisfies.  Jesus has abandoned himself to death, in order that we might be brought back home, and dwell for ever in the new heavens and new earth.
4. The presence of God and worship.  Our sin is, at its heart, idolatry, the worship of other than the true and living God.  But Jesus has opened up the way of access to God again, Heb 10:19-22.
5. Rest and Sabbath.  In Christ, we cease from the toil of trying to be ‘good enough for God’, and rest in his unconditional acceptance.
6. Justice and judgement.  We yearn for justice, but then if there is a Judge, what hope is there for any of us (Psa 130:3)?  But Jesus has come, not in condemnation, but to deliver us from condemnation.  He was judged so that all who believe in him can face the future judgement day with confidence.
7. Righteousness and nakedness.  When we lost our original righteousness, we sought to cover our nakedness and his from God’s penetrating gaze (Gen 2:24-3:24).  But Jesus was stripped naked so that we could be clothed with his righteousness (Isa 61:10).
