The strongest rope is a threefold rope. The largest number of strands that can all touch one another is three. If you take one away and leave only two, obviously the rope will be weakened. If you add an extra strand and make four, you do not add to the strength of the rope because the strands no longer touch one another. If you have a rope of three strands, one or two of the strands may be under pressure and start to fray, but as long as the third strand holds, the rope will not break. God is the third strand, touching both lives and becoming an integral part of the relationship making for a stronger marriage.
