What does the Bible mean by the lamb must be examined?

In Exodus 12:5, the lamb chosen for the Passover was to be without blemish for four days before slaughter. This examination stands as a crucial type foreshadowing Christ, who is depicted as sinless and perfect in His nature. The call to examine the lamb emphasizes the necessity of recognizing Christ's qualifications and His sinlessness to secure our salvation. As the preacher articulated, while humans may have flaws, Christ is the flawless lamb, manifestly suitable for sacrifice and worthy of our faith. This examination underscores the holiness of God and how only through the perfect lamb can we be reconciled to Him.
