How do we know that God is the chief planter?

God's unique role as the chief planter is established in biblical texts that distinguish Him as the source of spiritual life. In Isaiah, God describes His people as a vineyard He has planted, indicating that He is the one who establishes and nurtures spiritual growth (Isaiah 5:7). Similarly, in Matthew, Jesus highlights that any plant that His Father has not planted will be rooted up (Matthew 15:13), emphasizing the necessity of divine initiation in the transformation of hearts. This underscores the belief that without God's sovereign work, no true spiritual life can exist.
