Is salvation free if repentance is required?
Repentance is the empty-handed turn that receives mercy, not a price equal to salvation. The Servant has borne the cost.

Verse and question study
What are the “sure mercies of David”?
They are God's reliable covenant promises of enduring Davidic rule, fulfilled in the risen Messiah and extended through Him to the covenant community.
Can there be a time when God may not be found?
Persistent refusal can harden the heart, and life has a limit. The verse presses present response rather than encouraging speculation about when opportunity ends.
Does verse 11 promise any quoted Scripture will produce the speaker's desired result?
No. God's word accomplishes God's purpose, which may include conviction and judgment as well as the outcome a human messenger hopes for.
Historical and literary context
The invitation flows from the Servant's atonement and Zion's restored covenant. “Free” does not mean costless to God; Isaiah 53 has shown the Servant bearing the cost. The Davidic covenant appears after the Servant Songs, indicating that the Servant fulfills royal as well as representative and sacrificial hope. The chapter concludes Isaiah 40–55 with assurance that God's word accomplishes restoration.
Apologetic note
Acts 13 interprets the Davidic covenant phrase through Jesus' resurrection, showing an early Jewish Christian reading grounded in the text's claim of enduring royal mercy. The chapter's free invitation is also logically connected to substitution in Isaiah 53, giving grace a moral foundation rather than portraying pardon as indifference to evil.
