“To Him all the prophets witness that, through His name, whoever believes in Him will receive remission of sins." Acts 10:43
To Him: Jesus and the gospel are inextricably one. We believe the gospel when we believe in Him.
All the prophets witness: Jesus was not ”Plan B,” or an after thought. It was God’s plan from eternity past to save His people through faith in Jesus. And God foretold this wonderful plan throughout the Old Testament by His servants, the prophets.
Whoever believes: Anyone and everyone who believes (trusts) in Jesus and what He accomplished on the cross by dying, and then by rising from the dead, will be saved. Anyone. Left to ourselves, as those dead in sin, no one would ever believe. But God in His sovereign mercy, regenerates His people, causing them to believe—and be saved!
Receive remission of sins: Remission (forgiveness) of sin is what is needed to be accepted by God and gain entrance into Heaven. Why? Because there is no sin in Heaven, so those who go there must have their sins entirely washed away. That is what Jesus accomplished for those who trust in Him!
