How do we know that God keeps His people safe?

In John 17:11-12, Jesus affirms that He keeps those whom the Father has given Him, stating that none are lost except the son of perdition. This assurance reflects the sovereignty of God in preserving His elect. Believers can trust that God's keeping power is rooted in His character and covenant promises. God ensures the perseverance of the saints, meaning that true believers will be sustained in faith until the end, evidenced by Philippians 1:6, which states that He who began a good work will carry it to completion.
