Grace to you and peace from Him who is and who was and who is to come (Revelation 1:4). Christ is the eternal Son of God. He was in the past. He is today, and He is forever. He came the first time to bring grace to sinners. He is the gift of God as our salvation (John 3:16). He is the one who brought us peace with God. He is the same one who shall come again.
The one who shall come loved us and washed us from our sins in His own blood (Revelation 1:5). Every believer experiences the love of God in Christ, through the Holy Spirit. We know God's love, because the love of God has been poured out in our hearts by the Holy Spirit who was given to us (Romans 5:5). We are forgiven and washed from our sins. That's because the blood of Jesus Christ His Son cleanses us from all sin (1 John 1:7).
The one who shall come is the firstborn from the dead and the ruler over the kings of the earth (Revelation 1:5). He is the first one to be raised from the dead in a glorified body never to die again. He rules over all (Matthew 28:18). Therefore, He shall come as King of Kings and Lord of Lords (Revelation 19:16).
The one who shall come died for our sins and was raised from the dead. Therefore, if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved (Romans 10:9).
