This is the first paragraph from Thomas Schreiner’s New Testament Theology:
The thesis advanced in this book is that NT theology is God-focused, Christ-centered, and Spirit-saturated, but the work of the Father, Son, and Spirit must be understood along a salvation-historical timeline; that is, God’s promises are already fulfilled but not yet consummated in Christ Jesus. We will see that the ministry of Jesus Christ and the work of the Spirit are fundamental for the fulfilling of God’s promises. The coming of Jesus Christ and the work of the Spirit are the prime indications that God is beginning to fulfill the saving promises made to Abraham.
This is one I’ll keep handy and refer to again and again. (I’ve already tabbed the Scripture index so I can look up passages I’m studying.)
