"Indeed, the theology of the New Testament can be summarized by the following sequence:
1. Indicative - "Christ died for our sins" (1 Cor 15:3)
2. Imperative - "Repent, and believe in the gospel" (Mark 1:15)
3. Indicative - "we...died to sin" (Rom 6:2)
4. Imperative - "Reckon yourselves to be dead indeed to sin" (Rom 6:11)
...The indicatives and the imperatives of the gospel do indeed lie in each other; they are interwoven and intertwined" - Carrick, IP, p23.
I would only add that the movement from indicative to imperative is only accomplished by grace through faith. We are not responding to the good news except God is at work in us to will and to do according to His good pleasure (Phil 2:12b-13).
