How do we know that rest comes from God?

Psalm 127:2 states, 'It is vain for you to rise up early, to sit up late, to eat the bread of sorrows: for so he giveth his beloved sleep.' This illustrates that genuine rest does not stem from human effort but is a divine gift for those who are in Christ. Worry and anxiety often plague us, but when we understand that God is in control and that our salvation is finished through Christ's work, we can experience true rest. Rest is associated with trusting in God's provision, reflecting that we do not gain security through our works but through His grace, enabling us to cease from our striving and to fully rely on Him.
