God gave me this wedding gift when we got married but I rarely used it :( We both know praying together is important but we would get lazy and occupied with things of life that we would simply skip it. If we have God at the center of our marriage, then prayer time together cannot be skipped. It's that simply. "The unity that grows between a man and a woman who regularly pray together forms an intense and powerful connection." It would be our way to humble ourselves to seek His guidance... because we know we can do no wrong with His advice.
A family that prays together stays together.
