Treasury of Scripture Knowledge
And [the need for] a change of heart and life in order to receive the forgiveness of sins [from God] will be preached in Jesus' name [i.e., by His authority] to people of all nations, beginning from Jerusalem.
It is written in the prophets [Isa. 54:13], 'And they will all be taught by God.' [So], every person who has heard the Father and learned [from Him] will come to me.
What shall we say, then? Should we continue sinning so that more of God's unearned favor will [have to] be shown?
2 Corinthians 5:14
For Christ's love for us motivates us, because we have concluded that, [since] one person [i.e., Christ] died for all people, so then all people have died. [Note: This may mean simply that Christ died for all people, who were dead in their sins].
For God's unearned favor has appeared, bringing salvation to all people [i.e., in the coming of Christ].
1 John 2:27
And this is important to you: The "special gift," which you received from God [See verse 20], continues to live in your hearts, [so that] you do not need anyone to teach you [anything different]. But, since this same "special gift" teaches you concerning everything that is true, and [what it teaches] is not false, you should continue to live in [fellowship with] Christ.
