Once you come to realize that all material possessions and earthly things will burn away, it changes your perspective. The world thinks that this earthly life is the sum of our existence and that everything within it is the sum of our reward. Based on that understanding, everything we do on earth matters in a way that has us pursue as much gain, reward and satisfaction as we can because one day, it will all come to an end.
How did Christ love the church? First, “[He] gave Himself up for her” (Ephesians 5:25b). That’s referring to the sacrifice Jesus made on the cross so that sinners like you and me can be saved. So if a husband’s love for his wife is to be like Christ’s love for the church, we could say that his love should be cruciform—in the shape of a cross.
