How do we know that salvation requires emptiness?

The sermon emphasizes that to be filled by God, one must first come empty. In 2 Kings 4, the widow was instructed to gather empty vessels without any mixture, symbolizing that we cannot bring anything of our own works or righteousness to God. Salvation can only be received when we recognize ourselves as spiritually bankrupt and empty, ready to be filled with God’s grace. As the preacher noted, many people may think their 'righteousness' or moral standing can contribute to their salvation, but it is precisely this self-righteousness that hinders them from coming to Christ. The act of coming empty reflects a heart ready for the transformative work of the Holy Spirit.
