But if you two are doing this thing together, there’s got to be a common sense of purpose and mission.
Without that, you spin your wheels alone and eventually get tired of explaining how you feel God’s calling on your life.
Can a Christian and a non-Christian date, fall in love, be genuinely happy, get married and do great things for the world? There are countless follower/non-follower relationships that would be viewed as phenomenal by any standard.
Additionally, it is possible for you to follow Jesus and bear fruit throughout your life even if your dating relationship isn’t rooted in Christ. But somewhere, at some point, you’re going to realize that you are building a life on two different foundations.
Maybe God has you right where He wants you and this relationship is about pulling her into the Kingdom, instead of drawing you away from God.
