“Yet I hold this against you: You have forsaken the love you had at first.” (Revelation 2:4)
The first love:
“Greater love has no one than this: to lay down one’s life for one’s friends.” (John 15:13)
“You see, at just the right time, when we were still powerless, Christ died for the ungodly. Very rarely will anyone die for a righteous person, though for a good person someone might possibly dare to die. But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. Since we have now been justified by his blood, how much more shall we be saved from God’s wrath through him! For if, while we were God’s enemies, we were reconciled to him through the death of his Son, how much more, having been reconciled, shall we be saved through his life! Not only is this so, but we also boast in God through our Lord Jesus Christ, through whom we have now received reconciliation.” (Romans 5:6-11)
The first love: God demonstrated his own love for us on the cross.
The first love, Christ Jesus dying for me who was his enemy at the time.
“Consider how far you have fallen! Repent and do the things you did at first.” (Revelation 2:5)
The things I did at first: rejoicing in the cross of Jesus Christ!!!!!!!
“This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins.” (1 John 4:10)
Jesus is the well of the living water, the Holy Spirit.
