Discontentment in Marriage

As we have announced with much joy the marriage this coming week of two from our very midst, I believe it would be beneficial for us all to take some time this Lord's Day and next Lord's Day to reflect on two sins that can do great damage in our marriages (and their spiritual remedies). This Lord's Day I would like to address the subject of discontentment in marriage (and its biblical remedy). Discontentment in marriage leads to looking for greener grass elsewhere (it begins by imagining how much better your marriage would be with ___, then looking and acting it out).
Discontentment arises when change does not come as you want it or as soon as you want it. Discontentment is chiefly not a marriage problem, but rather a spiritual problem in your relationship with Jesus. You're not content in Him. Will you choose by God's grace to learn contentment in whatever state your marriage may be, or will you sinfully choose to be swallowed up with discontentment as you face sorrow, heartache, or great trial in your present circumstances?
