For all things are for your sakes, that grace, having spread through the many, may cause thanksgiving to abound to the glory of God.
2 Corinthians 4:15 (NKJV)
Grace causes us to be thankful because grace is the revelation that everything we need has already been made available. As we walk in this by faith, one day and one moment at a time, our gratitude gives glory to God. And God’s glory always shows itself in the lives of His people as the very manifestations of His favor and goodness.
