My parents were humanist, and the word "God" was a three letter word, never spoken in our home. My paternal grandmother was a Christian, and she witnessed to me and prayed for me.
On the other hand, my parents were extremely strict, and they gave me no reason to follow Christian values they lived by. They just told me it was right to live by these Christian principles while living pluralistic and relativistic in word, and Judeo Christian laws in deed. So I rebelled, and went far astray in my teens.
I think consistency is very important in raising children. If you believe in Christ, then you need to act according to his words. I think it was hypocritical of my parents to tell me that science had all the answers, but to live by Christian values.
Because the two in the 50's and 60's were very far from each other.
However, I was sent to Baptist Sunday school in my childhood, where I learned a lot of the Bible, and also probably heard the gospel enough to know what it was. We also went to the Unitarian Church when I was a young teenager, which was like being in a social club on Sunday mornings.
Anyway, I wish more love had been shown, but God knew what I needed so that one day I would repent and believe, and that is all that really matters!
