That's not what a "calling" is. That's more like a destiny. A calling is, by definition, an earthly vocation.
You are defining what a calling is and then saying what it is by that definition.
A calling is what we are called to. God is calling us to Heaven and there, we will find a life of celibacy, as there is no marriage there.
If you believe in scripture and you believe that we are called to Heaven, then we are called to celibacy.
We will also not require food in Heaven. Does that mean we should not eat here on earth? No, God gave us stomachs and food for a reason. He also gave us sex drives and marriage for a reason. Once again, there is nothing holier about celibacy than there is about marriage. If God has called one to either, then that way is right for him. Neither those who marry nor those who remain celibate are engaging in a "higher calling" than the other, any more than a doctor has a higher calling than a farmer, or vice versa. To say otherwise is to attempt to divide human beings into greater and lesser moral categories.
Except that food is necessary for life, being married is not. The Gospel does not promote not eating food, but it does promote celibacy.
Here is what scripture (1 Corithians 7) says:
"Now concerning the things about which you wrote, it is good for a man not to touch a woman."
"But I say to the unmarried and to widows that it is good for them if they remain even as I. But if they do not have self-control, let them marry; for it is better to marry than to burn with passion."
"But I want you to be free from concern. One who is unmarried is concerned about the things of the Lord, how he may please the Lord;
but one who is married is concerned about the things of the world, how he may please his wife,"
Revelation 14:
"These are the ones who have not been defiled with women, for they have kept themselves chaste. These are the ones who follow the Lamb wherever He goes. These have been purchased from among men as first fruits to God and to the Lamb."
Marriage is an Earthly vocation. But we are no longer mere natural humans, but share in a supernatural existence in Christ. Thus, it is appropriate for Christians to be celibate and live out their ultimate calling. That does not mean that choosing the natural and not the supernatural route is bad. But to say that something of Earth (marriage) is equal to something of Heaven (celibacy) is totally wrong.
