How do we know Jesus Christ was faithful?

The sermon highlights that Jesus Christ has always been faithful, as seen in Proverbs 8:28-30, where He is depicted as being with God before creation. His faithfulness continued when He was born as a man, as illustrated by His obedience to God’s will throughout His life. At His baptism and during His transfiguration, God the Father affirmed Jesus' faithfulness, stating that He was well-pleased with Him. This constant fidelity is what distinguishes Him from fallen humanity, which cannot claim such faithfulness on its own.
