In Genesis, God describes a good partnership in marriage as being that of a "suitable helper." In Luke 10, Jesus told His disciples, "The harvest is plentiful, but the laborers are few. Therefore pray earnestly to the Lord of the harvest to send out laborers into his harvest." (v2)
When looking for a spouse, what's your primary concern? Mine's to get a fellow laborer for Christ, who is thus truly an ideal helper in the work for God!
