How do we know that God's grace sustains us in hard times?

The sustaining grace of God is a recurring theme throughout Scripture, especially highlighted in the account of Elijah. When Elijah fled from Jezebel's threat, he encountered despair and exhaustion. But God, in His mercy, sent an angel to provide nourishment and reassurance, emphasizing that His grace is sufficient for our needs. This is further exemplified when God said to Elijah, 'the journey is too great for thee,' reminding him that he needed divine support to continue. God's grace doesn't just sustain us spiritually but meets our physical and emotional requirements too, assuring us that we are never alone in our struggles.
