1 John 4:10–In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins. 
When was the last time you worked diligently hard to love someone, when you couldn’t “lean on” immediate affection and adoration?  Maybe because of an argument, a bad choice/mistake, or maybe long term “coldness” from the other person, has that caused you to really seek God, and fight in prayer to love?
We may not recognize it , but a life of seeking “comfort” over God, robs us of the ability to really fight to love someone unconditionally.  That if my mentality is to compromise, the uncomfortable conviction of faith, obedience, and sacrifice in a relationship to God.  Then the inevitable carry-over, is to avoid the uncomfortable call to love unconditionally someone who is certainly not perfect like Jesus!
The apostle John makes a point for us to realize, that love does not originate from us, because God is love.  So for the Christian, if we don’t seek God to first receive love, how capable are we to carry out love?  Not only to those we may truly love in our families, but enemies, strangers, etc.  So when Jesus tells us to love our enemies, that sounds crazy if I struggle to love my own spouse or child! (Luke 6:35)
The call to really love people seems impossible, if we don’t have a prayer life and time in God’s Word to receive.  If we are not receiving from God, the affections we do have tend to fade, and they generally fade with people’s performance or lack thereof.  So “falling out of love” makes sense if love originates and is sustained by us.  But falling out of love, and falling back into love is possible, if we are receiving from God, who is Love…(Matthew 17:20, 1 John 4:13-21)
I believe when we don’t truly seek God for His love, in order to truly show love to others, we fall victim to societal pressure to pretend, or carry out the act, without the heart of affection from true love.  Christians shouldn’t allow the phoniness of the world’s definition of “love” without God, to be hijacked and presented as cute or easy.  Especially when God defines love as His Son brutally dying to prove it, that we not live powerless to love people.  Our fight to love, proves we honor and receive His love. (1 John 4:16)
In His Love, Ld
