God identifying Jesus is His Son.
God the Father is speaking to Peter, James and John saying that Jesus is His son and that they should listen to Jesus. An audible voice from the Father in heaven was also heard by bye standers at Jesus baptism saying the same thing, this is my beloved son listen to Him.
Because Jesus had not gone to heaven yet.
God's way of doing things
What do you mean? Jesus was already perfect and new everything.
Acording to Scripture we enter the Kingdom of Heaven through Baptism. At the time of Jesus John was baptising and many came to be baptised even those, it would seem, who believed that Jesus was the one who would free Israel from Roman occupation. We also know that Pharisees who were referred to by John as a "brood of vipers" came also and it seems that no one was turned away.
God is up in Heaven, but this does not mean he is the first person you meet in Heaven.
Jesus means he is the only person who can give you life, show the way to heaven.
She is our mother. We can ask her to pray to Jesus for us since she is in heaven with Him.
I'm not totally sure what you mean by a 'baptism card'.. I was baptized as sign/ vow to God and others that i would live for Jesus my whole life.
Laniweke - [la-nee-vay-kay] - a little crack (opening) to heaven
If you mean where were Jesus half brothers while he spent 3 years traveling around Israel then they were in Nazareth. If you mean now they are most likely in Heaven with him.
Once. Baptism is to erase the original sin. Confession is for the sins you commit after baptism. I guess if you wanted it to actually mean something , twice. You could get baptised the same way Jesus did.
