I have something similar going on at my place, here’s my experience…my elder son at around 21 wld only go to church if we insisted. It was, most times some excuse or the other. I had a talk about this with him. He straight out explained, it was boring, he had no relationship with God, and found it pointless going to church every Sunday. He said he came out of obedience n respect n love for me. I then told him he got it upside down he shouldn’t be doing it for me, but for God. I discussed this with my parish priest who advised not to push. Best advice ever!
I did just that. But every time, I asked in the sweetest possible mums voice if he was joining us for mass, or rosary, or adoration or even if he was coming for confession. He was surprised with that change. I told him you’re old enough to make decisions, but every now n then I tell him, don’t let go off Gods hand ever… even if you’re just hanging on to his pinky finger, keep holding don’t let go. He smiles n says no mum I won’t. As mum, I will occasionally send them msgs about, feast days, holy days, reminders abt fasting, or blessings.
He travels a lot n will sometimes send me a pic at the church where he went for Sunday Mass, captioned “just so you know…” Sometimes he will choose going to a BBQ over Sunday Mass, n other times Im just surprised he decided to choose going to church instead.
Once I questioned this n he says 'Jesus is my buddy he understands I don’t want to hang out with HIM all the time, HE maybe yr best friend but not mine as yet, so you keep your relationship going, n I’ll worry about mine.
My younger son, 5yrs his junior, is surprisingly not following in his footsteps which I was so worried about he’s 19 & will faithfully make it to church every Sunday with girlfriend in tow, who happens to be of a different faith. Few days ago, out of the blues he went to church to inquire about serving mass.
What I’m trying to say is, they need to have a relationship with God to want to be in HIS house, to share in HIS Goodness, n Blessings n Love. Forcing isn’t going to help. It’s nothing about you having failed as a mom either. We mom’s are always learning what works n what doesn’t. After all life doesn’t hand us a manual for our specific model of a child ! God knows you’re trying, ask HIM to bless your tiny efforts to lead your child to HIM.
Pray, do your best n leave yr child in Gods hand to do the rest. That’s is what faith is all about trusting in the one above.
