Indicative and imperative in Matthean soteriology

It is usually thought that Matthew emphasizes the imperative at the expense of the indicative, demand over gift. Identifying Matthew's indicative is difficult because in chapters 5-25, insofar as disciples are concerned, the narrative is told in terms of "omnipotence behind the scenes". In Matt 5-25 four techniques appropriate to such a method of narration speak of the divine indicative in relation to the imperative. They are (1) I am with you/in your midst, (2) invoking the divine name, (3) it has been revealed to you/you have been given to know, and (4) being with Jesus. They show Matthew's soteriology is by grace from start to finish.
