Revelation 1:4 NKJV
John, to the seven churches which are in Asia: Grace to you and peace from Him who is and who was and who is to come, and from the seven Spirits who are before His throne,
As John, the beloved writes to the seven churches of Asia, he sends a blessing of peace from the Lord. He describes God as the One who is, was and is to come. In other words, the author of our peace is always present with us. That is not subject to change. So if at any time peace seems to be missing, it is not hard to recover it. He who never leaves nor forsakes us is the source of our peace. Let us remember that and act like it.
