How do we know that God saves some people?

The assurance that God saves some is grounded in the revelation of Scripture, notably in Ephesians 1:4-5, which states that God chose certain individuals in Christ before the foundation of the world. This doctrine of election highlights God's sovereign choice to save some from the fallen human race. The believer's confidence in this truth comes from resting on God's Word, realizing that His decisions are made according to His own good pleasure and grace. For those who trust in Christ, this assures them of their identity in Him and the certain hope of salvation.
