In their ground breaking book “When God Writes Your Love Story”, couples Eric and Leslie Ludy shares what it means in having contentment in Christ in your singleness:
A relationship is not meant to make us into a whole person—only Jesus Christ can make us a whole person. Marriage should never become that gold medal we strive for that will finally make us ‘enough’. We must learn to be ‘enough’ right now, just as we are, in Christ alone.
While getting married someday may bring us great joy, we truly do have a reason to be happy and content no matter what season of life we are in—because of what Jesus Christ has done for us. True contentment can only be found in intimate love relationship with the Lord, not in anything else, including a romantic love story. Singleness can teach us thus contentment. In this season we can learn what it means to have peace and joy in Christ, no matter what our circumstances may be. And in a culture that is always longing for something more, ‘…godliness with contentment is great gain” (1 Tim 6: 6 NIV).
