According to evangelical Christian belief, the most likely author of Matthew 4:4 is the Apostle Matthew, also known as Levi. Matthew was one of the twelve disciples chosen by Jesus to follow him and spread his teachings. He was a tax collector before he became a follower of Jesus, and his gospel is considered one of the synoptic gospels, along with Mark and Luke.

Evangelical Christians believe that Matthew was inspired by the Holy Spirit to write the words of Jesus in his gospel, including the verse in Matthew 4:4 where Jesus says, “Man shall not live by bread alone, but by every word that comes from the mouth of God.” This verse emphasizes the importance of spiritual nourishment and the word of God in the life of a believer.

Overall, evangelical Christians view Matthew as a trustworthy and reliable author of the Bible, whose gospel provides an important account of the life, teachings, death, and resurrection of Jesus Christ. They believe that the words recorded by Matthew are divinely inspired and provide guidance and wisdom for believers in their walk with Christ.
