How do we know salvation is only through faith in Christ?

Faith in Christ is the sole evidence of being among the elect of God. According to Romans 8:30, those who God predestines, He also calls, and those whom He calls, He justifies. This unbreakable chain affirms that true faith is a result of being chosen by God before the foundation of the world. Believing in Jesus Christ demonstrates that an individual has been effectively drawn to Him by the Holy Spirit. This ensures that salvation is not based on human effort or merit, but solely on the sovereign will of God and the work of Christ. Ephesians 2:8-9 underscores that salvation is by grace through faith, and this not of ourselves; it is the gift of God.
