How do we know that Jesus is truly the anointed one?

Jesus' identity as the anointed one is validated through His fulfilled prophecies and the miraculous works He performed during His ministry. In Luke 4:21, after reading from Isaiah, Jesus declares that 'this day is this scripture fulfilled in your ears.' This statement asserts His role as the Messiah, confirming that He embodies what the prophets foretold. Additionally, the signs accompanying His ministry, including healing the sick, raising the dead, and teaching with authority, further affirm His anointing. His life and works are evidence of divine purpose, consistent with the promises made by God through the prophets throughout the Old Testament.
