I think you totally miss my point. Of course kid's can take part in parents activities including ministry etc. However my point. Do not push them. Letting them know how capable (stout ? - we have a word for this in my native language that has no direct translation in english) they are. Unwittingly giving them a feeling of "competition" of "spiritual maturity" from way too young age . These imperfect habits often transferres into adulthood when people need "labels" to tell others how "spiritually successful" they are (elder, bethelite, CO etc. etc) instead of imitating Jesus standards being humble and loving (Luke 9). If we are not cautious this "pattern" can easily being "planted" into our kid's. One example is the PRISING of young ones getting baptised. "The younger the more praiseworthy". I don not generalise here, but I can see these tendencies (see 1 Peter 1:7 and the baptism questions and ask yourself: "Is this appropriate for an 8/9/10 etc yr young kid to be answering?")
My point is that maybe parents should be very much aware of these tendencies and therefor resist/contain them trying to find a healthful balance.
OK. I hope I have been able to explain my worries. I love kid's and I respect parents working hard to raise their kid's to become good/loving human beings/christians.
PS: What is your real identity/name? Always nice to know who you are talking to....
PPS: Please have in mind English only is my second language. Therefor I sometimes use the wrong word. Please try not to interpret to the hard/sever direction but to the milder.
