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

The assurance of God's sustaining grace is grounded in His character and promises. Paul reminds us in Romans 5 that tribulation produces perseverance, character, and hope. These elements are intrinsically linked, shaping our faith through experiences of hardship. James instructs believers to view trials with joy, recognizing that they are tools used by God for spiritual growth. Ultimately, we learn that Christ is our sustainer when we go through hardships and realize that our strength lies not in our own abilities but in His grace. This interaction with trials leads us to deepen our faith in God's eternal goodness.
