In closing, James reminds us of the power of prayer. This truth could not have come at a better time for first century believers, or for the twenty-first century believers. There is power in payer. Power to bring relief to those who suffer, power to heal the sick, power to forgive sin, and power to turn the heart of the wayward back to the Lord. James tells us that we don’t have to be a priest, a prophet, or an apostle to pray powerful prayers; we just have to live right and know who to call upon. The words “pray” or “prayer” occur seven times in eight verses, so prayer is clearly the theme of James at the end the letter.
In verse 5 John refers to “the message,” from the Greek anggelia, meaning “announcement, information, or message.” He says they received the message, the information, from Jesus and they were declaring it without distortion or apology. What is the message? It is “that God is light and in Him is no darkness at all.” God is pure light, meaning there is no impurity or imperfection in God. It is this message, this light from God, that exposes the lies, the falsehoods, and the deception of the heretics and opens the door for people of faith to have fellowship with one another.
