How do we know that true believers will never fall away?
Answered in 2 sources
Scripture assures us that God, in His sovereignty, preserves true believers and guarantees their perseverance in faith.
The idea of the perseverance of the saints is grounded in the belief that genuine, born-again believers cannot ultimately fall away from grace. As expressed in the sermon, the assurance comes from the sovereign acts of God, who keeps His elect secure. Passages like Philippians 1:6 remind us that God who began a good work in us will complete it until the day of Christ Jesus. Additionally, John 10:27-29 reinforces this by declaring that no one can snatch believers from the Father's hand. Therefore, the assurance of salvation rests not upon human effort but solely on God's faithfulness and power to sustain His chosen people.
