John Stott 
Focus on Christ [PDF ebook] 

It pleases the Father, Son and Spirit that the Son, Jesus Christ, be the centre of our worship, have the name above all names, and be first above all things. Everyone has a relationship with him — whether bearing his image but being estranged from him or knowing Christ as Lord and Saviour. In this book, John Stott draws our attention to how the New Testament speaks of Jesus Christ. He examines the prepositions used to help us understand more deeply, our position in relation to the Son of God. We are to live in Christ, through Christ, on Christ, with Christ, under Christ, for Christ, and like Christ — and this book will help you become truly Christ-centred.
