February 14 is Valentine's Day, named after St. Valentine. It's a day when couples get each other cards, chocolate, flowers, and other gifts. Some claim this day was invented by greeting card companies so they could sell more product. Whatever the cause, it's a good day to be reminded of love.
If we see a child playing and having fun, it would not be kind, or loving, to stop them. However, if the location of the play is on a street, or railroad track, and danger is approaching, it is loving to stop the child's enjoyment and move them. In the same way, when someone is living in sin, it is loving to warn them about the danger ahead.
Yes, God is love, but He is also a just and righteous judge that must see sin punished. If you do not repent of sin and do everything possible to keep from it, then justice will be served. Unfortunately, many churches just preach the first part and forget the second.
As sinful men and women, God showed His love for us by Jesus' death on the cross and paying our debt. All who repent and put their faith in Him alone will be saved. We demonstrate our love for God by following His commands, reading His word, and telling others about the gospel. It can seem unloving to show sin in someone's life, and needs to be done thoughtfully, but we cannot give a solution unless the problem is known.
Throughout this day, and week, remember how God demonstrated His love for us, and extend it to all around us.
