How do we know true faith is from God?

True faith is identified not by human effort but by the work of the Holy Spirit within us. As mentioned in John 3:8, the Spirit moves sovereignly, indicating that faith is a work of God rather than a simple human choice. Romans 9:6 affirms that not all who are of Israel belong to the true Israel; it is through God's elective grace that we come to possess genuine faith. A hallmark of true faith is its unwavering trust in God's provision, as exhibited by the Israelites' need for quail over the manna provided, showcasing their lack of faith in divine sustenance. A true believer will see God's faithfulness throughout their life and will not rely on their own merit or understanding.
