How do we know that Jesus sees our hearts?

The assurance that Jesus discerns our hearts is grounded in the Word of God, as illustrated in Revelation 2:23 where He proclaims His divine ability to search the reins and hearts. This is echoed in Hebrews 4:12, which speaks of the Word of God as sharper than a two-edged sword, penetrating to the thoughts and intentions of the heart. Jesus, as the embodiment of this Word, meets us at our core, evaluating our every intention. This truth compels us to embrace self-examination and genuine repentance, recognizing that our lives are fully known and understood by Him.
