How do we know the doctrine of saving grace is true?

The truth of saving grace is declared through numerous Biblical passages, emphasizing that salvation is a gift from God, not based on human effort or merit. Ephesians 2:8-9 illustrates that it is by grace we have been saved through faith, which underscores that our acceptance with God is grounded in Christ's sacrificial death. Furthermore, the lived experiences of believers, who demonstrate the fruit of the Spirit as evidence of their transformation, affirm the reality of this doctrine. Moreover, grace leads to a heart change that manifests in selfless service and love toward others, validating its truthfulness.
