How do we know that grace helps us endure until the end?

The endurance of believers until the end is rooted in the grace of God. In Romans 4:4-5, it is affirmed that God's grace is always sufficient for those whom He has justified. The Apostle Paul emphasizes that even when trials come, grace sustains and strengthens believers to remain steadfast in their faith. It is through grace that we can navigate life's challenges with the assurance that we are not alone and that God will provide the necessary strength to endure and ultimately reach the promised rest.
