It’s indeed a tall order or an impossible task to carry out, since definitely it requires the grace of God, our true identification with Christ, and not just our human efforts though these should also be used to the full.
It’s definitely no joke to be a disciple of Christ. It demands of us everything. This is how Christ himself described what to be his disciple requires:
“If anyone comes to me without hating his father and mother, wife and children, brothers and sisters, and even his own life, he cannot be my disciple. Whoever does not carry his own cross and come after me cannot be my disciple.” (Lk 14,26-27)
And he added that to effectively carry out our discipleship of him, we should plan things well. We should not just have good intentions. We have to be properly equipped with everything that Christ himself would provide us. And this is nothing less than for us to be truly identified with Christ.
With Christ, everything will be put in order. We would know how to understand his words that at first may sound harsh and even inhuman to us—what with him telling us to ‘hate’ our father and mother, children, brothers and sisters.
We will understand that what he meant is that we give our whole heart to him, and by doing so we would actually know how to love everybody and everything else in the proper way. Our usual problem is that our human loving tends to be disorderly, fueled mainly by earthly and temporal principles and missing the real source of love.
To be a true disciple of Christ requires a certain kind of detachment so we can have the proper attachment to God and everyone and everything else in their proper order.
This is how he expressed it: “Seek first the Kingdom of God and his righteousness, and all these things will be given to you as well.” (Mt 6,33) We also know that among the 10 commandments, the first among those related to our duties towards others, the 4th commandment, is that of honoring our father and mother.
We need to have a certain detachment from persons and things to be able to give our heart entirely to God, and with him, we actually have everything we need. As St. Teresa of Avila put it graphically, with God we have enough—“solo Dios basta.”
So, the detachment our Lord is asking of us actually does not mean that we hate our life, our parents and others, and the things of this world. Rather it is a detachment that asks of us to have rectitude of intention, that everything that we do be for the glory of God.
St. Paul in his first letter to the Corinthians said as much: “Therefore, whether you eat or drink, or whatsoever else you do, do all to the glory of God.” (10,31)
We should train ourselves to have God first, last and always in our loving. This may require some discipline to control our human urges to let ourselves be guided and moved always by God’s love. This definitely will be a lifelong affair but we should consider as all worth it.
