How do we know that God fills empty vessels?

The assurance that God fills empty vessels is evident throughout Scripture. In 2 Kings 4, the widow's obedience in gathering empty vessels resulted in God's miraculous provision of oil that filled each vessel completely. This act signifies that God's grace is abundant for those who come to Him willingly. In the New Testament, we see parallels where Jesus speaks to those who recognize their need for Him. He specifically comes to call sinners and those who are empty, underscoring His mission to fill the hearts of those who trust in Him. The Apostle Paul also declares that believers are filled with the Spirit, implying that God's filling is continuous and rooted in faith and trust.
