Just thought I'd mention that.
Marriage is not a sprint. It's a marathon (with high hurdles). We all get weary along the way. We grow tired of putting the interests of others ahead of our own, dying to self, preferring one another in love, considering others more important than ourselves, speaking the truth in love, and bearing one another's burdens. That's not easy stuff, no matter how beautiful, talented or fun your spouse may be.
But here's what I've noticed in 15 years of marriage: when I do love my wife in any measure with our Lord's kind of self-sacrificing, practical love, there comes to my heart an inexpressible joy. Although It's hard to die to self, it's a JOY to live as Christ would live. Marriage is the perfect opportunity for sacrifice, for servanthood, for discipleship, for cross-bearing, for pain, for heartbreak, for perseverance, for suffering . . . and for glorious JOY!
