Jesus left no doubt as to who He was. Despite being clear multiple times throughout the Gospel accounts, Jesus words about Himself went misunderstood. Those who followed Him had an advantage we don’t. They walked with Him and saw Him and His miracles. Therefore it’s not surprising when someone hears about Jesus today and doesn’t believe.
The woman said to him, “I know that Messiah is coming he who is called Christ. When he comes, he will tell us all things.” Jesus said to her, “I who speak to you am he.” – John 4:25-26, ESV
Here is one example of Jesus making a claim to who He was. Now, He did this to the Samaritan woman and not in the presence of His disciples. However, He did so in their presence multiple times as well. He did not hide who He was. Jesus made a hard claim to being the Messiah, the one who would save His people.
This is why some Christian apologists will say that the Biblical accounts don’t support the idea that Jesus was merely a great man or even “just” a prophet. And this is why they will also say that if you don’t accept His claim about Himself, you must either classify Him a madman or a liar. They are correct on both points.
Jesus, based on the rest of the testimony of Scripture, was who He said He was. He was Messiah, the Christ, God’s Anointed. He came to save us from our sins. He came to teach us and help us better understand how to love, worship, and serve God. Jesus was and is God.
Jesus’ ministry to the woman and to the Samaritans was just getting started. He did have more to tell them. We don’t have what all He said or did. We are blessed to have the important points recorded for us in God’s Holy Word, and not just the interaction with the Samaritans, but many more situations. In addition, we have the revealed Word which God has shared to us through His prophets. It is a waiting resource for us to tap. Let us endeavor to do so!
