Revelation 1:4-5a; Him Which Is, Which was and Which is to Come
Revelation 1:4-5 John to the seven churches which are in Asia: Grace be unto you, and peace, from him which is, and which was, and which is to come; and from the seven Spirits which are before his throne; 5 And from Jesus Christ …
The Apostle John sends greetings from the Triune God to the seven churches in Asia. He pronounces the bestowing of grace and peace from God the Father – “from Him which is, and which was, and which is to come”, and from the Holy Spirit – “from the seven Spirits which are before His throne” and from God the Son – “from Jesus Christ”.
God the Father is described as Him which is, and which was, and which is to come, the eternal God, Who as there in the past, and is now here with His people in the present and and will be with them in the future. He will be there to meet with them in the future. He will not have a fleeting existence to disappear in the future. He is the Self-Existent Eternal Father in heaven reigning in the past, present and future.
