And God spoke all these words: “I am the Lord your God, who brought you out of Egypt, out of the land of slavery. You shall have no other gods before me…"
— Exodus 22:35-40
In the Old Testament we are told by God that we are to have nothing in our lives before Him - no other gods. The commandment goes on to say we are not to make and worship idols. Other gods and physical idols of the Old Testament were indeed worshipped by other tribes and nations. In our lives today the lesser gods and idols are those things we hold in such deep esteem that they come before God in our lives.
Then one of them, which was a lawyer, asked him a question, tempting him, and saying, Master, which is the great commandment in the law? Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets.
— Matthew 22:35-40
Here in the New Testament we see that Jesus puts love of God before love of any human person. This is the order in which we need to order **our **love: God first, others second.
Jesus also tells us that we are not given in marriage to one another in heaven, that the human marriage covenant is not eternal. However, the union we have with God, as individuals, is meant to be eternal. Human marriage and other relationships are just a foretaste of the relationship we are to have with the Triune God. That is the first relationship we must focus on, our relationship with God, all other relationships come after that.
This is not to say that our human relationships are not important. We are all part of the Body of Christ and, as St. Paul reminds us, one part of the body cannot tell another part that it is not needed. We are all in this together but each of us has an individual path to God. We cannot save one another - only Jesus does that. We can, however, help one another along in our spiritual journeys. A husband’s job is to help his wife get to heaven but he cannot sacrifice his own soul for the sake of any other thing-or person. Without his own ‘connection’ with the Almighty he’s of no use in helping someone else.
It’s all a matter of priorities. Many things are important to us but God must always hold first place.
