If we’re dishonest, unfaithful, selfish, then God can’t give his gifts to us because God’s gifts are little bits of Heaven and if God gives Heaven (or even a tiny piece of Heaven) to a dishonest or unfaithful or selfish person he’s creating hell, turning Heaven into hell.
It’s a bit like a business owner promoting a dishonest employee – disaster, the business will be lucky to survive.
So, the bottom line here is if you’re offending God, you just can’t receive much of Heaven or God’s gifts.
No, you must change your ways first.
So, another important part of preparing for Confirmation is making a firm commitment to change our lives so that it is possible for God to give us his gifts. Basically, God needs to be able to trust us with his gifts.
Once again, I invite you to consider celebrating the Sacrament of Reconciliation (Confession) since an essential part of every Confession is a firm commitment to change our lives, to become trustworthy of God’s gifts.
