How do we know Jesus Christ could not sin?

The assertion that Jesus could not sin lies in His nature as God. As the immutable God, He cannot change or choose to sin. He was tempted genuinely, but His divine nature ensures that temptation does not equate to the possibility of sin. This understanding is crucial, as some may argue that if He could not sin, His ability to resist temptation lacks virtue. However, His resistance stems from His nature as God. He faced temptations that mirrored our struggles, yet He emerged victorious. His refusal to submit to temptation confirms His holiness and reveals the profound nature of His identity as our Savior.
