We love, because he first loved us 1 John 4:19; Nevertheless I have this against you, that you have left your first love. Revelation 2:4; And Jacob served seven years for Rachel. And they seemed unto him but a few days, for the love he had to her. Genesis 29:20.
Thoughts on your First Love : You are totally silly with love - “It is looking at him across a room and feeling that if I don't spend the rest of my life with him, I'll have missed the boat.“; Jacob worked 14 years for Rachel.
What is this love?
Your first love probably falls between affection and passion: Phileo : To have a special interest in someone or something, have affection for, like, consider someone a friend, like to do something. Brotherly love and sisterly love - philadelphia (Romans 12:10); But we are never commanded to love God using this word: Jesus differentiates between this and agapao John 21:15-17.
Aagapao (n) or Agape (v): don't muddle with phileo. (1 Corinthians 13: 1-4). This type of love can be known only from the action it prompts. It is not the love of complacency or affection. This type of love is not drawn out by any excellency in it objects. Corinthians 12:15, John 13:1,24. Jesus differentiates phileo and agapao in John 21:15 when talking to Peter
Eros: passionate love, with sensual desire and longing. Cf “to know“ in the OT - 1 Samuel 1:19 - it must be contained by agape.
As love matures (1 Corinthians 13) The essence of love: Christ loved the church and gave Himself up for her (Ephesians 5:25). Can you remember your first love for Christ? First love gives up self. “I die daily“ 1 Cor 15:31 cf. Romans 12:1,2 A living sacrifice . Ask a question - have you lost this first love, or is it fading?
How do we prevent losing our first love?
Remember that we love because God first loved us 1 John 4:7, 1 John 3:16, 1 John 4:9 (read all of 1 John). Know that it is commanded by God Mat 5:43, 44; Matt 22. Love is an action that is always outward looking. Our ability to continue loving others is not of ourselves, but of Christ. Love must grow - cf Jacob
When it fails
Repent: 1. Stop doing what you are doing, 2. Turn around and face the other way, 3. We must change our mind - for this is what the Greek literally means. “Do the works you did at first“ 1 John 3:18, Hebrews 10:24. Pray for each other Ephesians 1:15 (church activity). We must also turn from what we should not love - the world and its things. 1John 2:15; We must re-examine the love of the Father - in this we will see what true love really is. 1 John 3:1
