How do we know limited atonement is true?

The doctrine of limited atonement, which asserts that Christ's atonement is applicable only to the elect, finds its basis in various theological interpretations of Scripture. Acts 13:48 states, 'And as many as were ordained to eternal life believed,' indicating that the grace of God operates specifically towards those whom He has chosen beforehand. This reinforces the belief that Christ's death was not universally for all but was specially meant for the elect, thus providing assurance that salvation is effective and secure for those selected by God. The understanding of God's grace as limited to the elect is further supported by passages that outline God’s sovereign plan throughout biblical history.
