When condition is improperly taken, and signifies no more than what particular duties as performed must, in the order of nature, precede the enjoyment of particular promised benefits, many things may be called conditions; for holiness must precede eternal happiness…. True repentance of sin must precede God’s fatherly pardon of it… And as faith is particularly required in the public dispensation of this covenant by the gospel…and is the appointed instrument by which God communicates, and we receive the blessings of it… it is more frequently called the condition of it, by divines: and indeed might be called a condition of connection in it. But when condition is taken properly for that which, when fulfilled, give gives the covenanters for right to claim the promised reward, nothing but the finished righteousness of Jesus Christ, by which all the demands of the broken covenant of works are fully satisfied, can be allowed as the condition of this covenant. 1. Christ took upon himself the whole death of his elect world,—all that of which the payment secures them from eternal death…and entitles them to eternal life…—nothing can remain there for to be fulfilled by them, as the proper condition of this covenant….
… 6. As our faith, repentance, and new obedience, by no means, answer the demands of the broken law, so, instead of being proper conditions of this covenant of grace, they are all in estimable benefits promised in it, upon the footing of its fulfilled condition…

Kline. God, Heaven and Har Magedon (Wipf & Stock, 2006, p 102 )—-Abraham’s obedience had typological import. The Lord constituted it a prophetic sign of that obedience of Christ, which merits the heavenly kingdom for his people. Abraham’s obedience functioned not only as the authentication of his faith for his personal justification but as a meritorious performance that earned a reward for others . . .” .
“Abraham’s faithful performance of his covenantal duty is here clearly declared to sustain a causal relationship to the blessing of Isaac and Israel. It had a meritorious character that procured a reward enjoyed by others… Because of Abraham’s obedience redemptive history would take the shape of an Abrahamite kingdom of God from which salvation’s blessings would rise up and flow out to the nations. God was pleased to constitute Abraham’s exemplary works as the meritorious ground for granting to Israel after the flesh the distinctive role of being formed as the typological kingdom, the matrix from which Christ should come… The obedient Abraham, the faithful covenant servant, was a type of the Servant of the Lord in his obedience.”

concerning conditions, it seems that we must distinguish…very carefully
