All close relationships, especially marriage, lead people either nearer to heaven or hell

From J.C. Ryle's comments about Luke 2:41-52:

Marriage is a state of life which has the greatest effect on the souls of those who enter into it. It helps them upwards or downwards. It leads them nearer to heaven or nearer to hell. We all depend much on the company we keep. Our characters are insensibly molded by those with whom we pass our time. To none does this apply so much as to married people. Husbands and wives are continually doing either good or harm to one another's souls.

Let all who are married, or think of being married, ponder these things well. Let them take example from the conduct of Joseph and Mary, and resolve to do likewise. Let them pray together, and read the Bible together, and go to the house of God together, and talk to one another about spiritual matters. Above all, let them beware of throwing obstacles and discouragements in one another's way about means of grace. Blessed are those husbands who say to their wives as Elkanah did to Hannah, "Do all that is in your heart." Happy are those wives who say to their husbands as Leah and Rachel did to Jacob, "Whatever God has said unto you, do." (1 Sam. 1:23; Gen. 31:16.)
