2 Samuel 19:33 (NIV)
I will provide for you.
The grace of God is always fresh, like a river flowing through us. There is nothing stale about God's grace or goodness. The only thing that prevents God from showering us with a fresh dose of His grace is sin. Disobedience, unrepentant sin, self-reliance, unforgiveness and many such are the reason why a child of God is not flooded with God's goodness every morning. If there's something stale about our walk with Christ, then we ought to get alone with the Holy Spirit and find out why, because God's goodness is fresh every morning and limitless.
