For the Gospel reveals how a person can be made right with God. It is through faith [in Jesus], from beginning to end, just as it is written [Hab. 2:4], "The righteous person will [obtain] life by [his] faith [in God]."

But now [i.e., under the Gospel age], a way of being considered right with God apart from [any] law has been made known. [The writings of] the law [i.e., the Pentateuch] and the prophets bear witness to this.

For they did not know about God's way of making people right with Himself, so they attempted to establish their own way. In doing this they did not submit to God's way for being made right with Him.

Shall not tarry

[Hab. 2:3-4 LXX says], "For [it will be] only a short time [before] He [i.e., Christ], who is coming, will be here without delay.

Salvation

For it says in the Scripture [Isa. 28:16], "Look, I am placing a stone in [the city of] Zion [i.e., Jerusalem]. It is a specially selected, very valuable cornerstone. And the person who trusts in the Him [i.e., the One represented by this stone] will never have to suffer shame [i.e., because of unforgiven sin being brought up against him]."

Israel

And everything I have belongs to you, and what you have belongs to me; and I am honored through these men.

so that we would praise His glorious, unearned favor, which was freely given to us through the One whom God loved [i.e., Christ].

On that day Jesus will return to be honored by His saints [i.e., God's holy people] and to be marveled at [i.e., in reverence] by all those who had believed [in Him]. [This will happen] because you have believed our testimony to you [about Christ].
