From an evangelical Christian perspective, the most-likely author of Deuteronomy 6:6-7 is Moses. This passage is part of the book of Deuteronomy, which is traditionally attributed to Moses, the leader of the Israelites during their exodus from Egypt and their time in the wilderness. Evangelical Christians believe that Moses received the Law directly from God and then communicated it to the Israelites, so it is widely held that he is the author of the book of Deuteronomy, including this particular passage.

Deuteronomy 6:6-7 emphasizes the importance of passing down the commands and laws of God to the next generation. It instructs the Israelites to “impress” God’s commands on their children, talking about them when they are at home or away, when they lie down or get up. Evangelical Christians view this passage as a call to prioritize the spiritual education and upbringing of children, and they see Moses as the authoritative figure who delivered this message to the Israelites.

Overall, evangelical Christians regard the book of Deuteronomy as part of the inspired and authoritative Word of God, and they affirm Moses as the primary author of the book and its teachings.
