I believe it should be at an age when the child can fully understand the stand they are taking and why they are taking it.
When it has reached the age of majority, in the UK, 18. Providing it hasn't been indoctrinated by parents and state, it is then old enough to make the decision.
Start teaching your child who introduced Baptism (Jesus Christ) and then why the adults got Baptised . Don't pay attention to anyone else but the Baptism that happened in the Bible (KJV).
They should be able to make that deshion for themselves.
John the Baptist who Jesus called the most holy of humans,had a ministry of baptizing primarily adults including Jesus mself who was not baptized until He was approximately 30 years of age. Matthew 3:13-15 13 Then Jesus came from Galilee to John at the Jordan to be baptized by him. 14 And John tried to prevent saying, “I need to be baptized by You, and are You coming to me?”15 But Jesus answered and said to him, “Permit it to be so now, for thus it is fitting for us to fulfill all righteousness.
” Then he allowed ANY discussion of baptism must include a mention of the much more important and separate baptism,the Baptism of the Holy Spirit, which only comes from God in response to fervent prayer. John 3:3-7 3 Jesus answered and said to him, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.”4 Nicodemus said to “How can a man be born when he is old? Can he enter a second time into his mother’s womb and be born?
”5 Jesus answered, “Most assuredly, I say to you, unless one is born of water and the Holy Spirit, he cannot enter the kingdom of God.6 That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.7 Do not marvel that I said to you, ‘You must be born again. ’.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
