What does the Bible say about how God sustains His church?

According to Psalm 147, God sustains His church by feeding it, not only providing physical nourishment but also spiritual sustenance through His Word. The beauty of creation is a testament to God's generosity; just as He causes the grass to grow on the mountains, He also provides growth and nourishment to His people. In His wisdom, the Lord sends trials (the clouds and rain) to feed His church, allowing it to flourish in unexpected ways. The sustaining grace of God includes both the provision of necessities and the spiritual growth of believers as they rely on Him.
