The Watch of the Lord, or watching in prayer, is very important to the plans and order of God. Jesus commanded us to “watch” with Him in several gospel accounts, particularly in the time called “the last days.” He described how we should respond when we see earthquakes, famines, wars and rumors of wars, and so on.
Jesus gave us the keys of the kingdom, and the keys include prayer:
"Again I say to you, that if two of you agree on earth about anything that they may ask, it shall be done for them by My Father who is in heaven. For where two or three have gathered together in My name, there I am in their midst" (Matthew 18:19-20).
Jesus wants groups of two or three people to gather in His name and ask in symphony or harmony. (The Greek word translated “agree” is sumphoneo, or “harmonious.”) This is the heart of the “watch of the Lord.” Studying God’s word reveals a model for prayer that is divided into eight watches covering 24 hours. Based on God’s creation, the days are counted from evening to evening as a day. “God called the Light Day, and the darkness He called Night, so the evening and the morning were the first day.” (Gen. 1:5)
