When we meet God in the gospel, we first encounter him as a stranger, come to rescue us from a danger we did not even realize we were in.
As Paul argues, it is the righteousness of God that is revealed in the law, and this condemns us all (Ro 1:18 – 3:20), while the gospel reveals the righteousness from God, namely, that we “are justified by his grace as a gift, through the redemption that is in Christ Jesus” (Ro 3:24).
Only when we start with the gospel - the most controversial point of Christian faith - are we ready to talk about who God is and how we know him.
The gospel isn’t just enough to justify the ungodly; it’s enough to regenerate and sanctify the ungodly. However, only because (in the narrower sense) the good news announces our justification are we for the first time free to embrace God as our Father rather than our Judge.
We do not read the Bible somewhere off by ourselves in a corner; we read it as a community of faith, together with the whole church in all times and places.
The object is evident in the name of the discipline. Similarly, theology (theologia) is the study of God. The object of theology is not the church’s teaching or the experience of pious souls. It is not a subset of ethics, religious studies, cultural anthropology, or psychology. God is the object of this discipline.
