Marriage is not about having a wedding; if you can afford its, that's fine. Marriage is God joining a MAN and a WOMAN together as a Couple.
What is important is to ensure that this Union is LEGALLY accepted in your location of stay and also to INVITE CHRIST to be the center of the union (that can be done in court or in church or in any other form based on the circumstances of the couple).
Living for the glory of God (such as bringing Christ at the center of our marriage) is for our benefit; its rest for our soul and not a religious ritual that makes you acceptable to God.
The only WAY to be accepted by God is to repent from living independent of Christ and to invite HIM into our hearts FIRST of all as our personal Savior and Lord
