Four ways to apply Christ by Tim Keller:
1) Theme Resolution
Certain theme run throughout scripture for example the theme of law and grace. Christ has fulfilled every theme of scripture. Christ met the demands of the law by living a perfect life and brings God's grace to us through His death.
This is preaching Christ from ethical principles. Every duty that we should perform has been completed by Christ. Every law points us to Christ because the law says to us ‘you can never fulfil me, you need a saviour' (Gal 3:24).
3) Story Insertion
The holistic narrative of scripture is the message of Jesus. Preach Christ from the story to be considered by looking for pictures of Christ in the text. For example: Jesus is the true Adam, Abel, Abraham….' Every story is about Jesus.
4) Symbol Fulfilment
Every major figure points us to Christ. The non-personal symbols point us to Christ. The entire sacrificial and temple system points us to Christ.
