Yes. I'm changing my mind and am beginning to agree with you.
But we used to say that when prayer in school stopped...
crime increased.
It is hard for us to make the right connections. We could also say prayer in school stopped and godless Communism fell. Cause and effect can be hard to discern.
Is it the job of the church?
Yes, and if we see them failing at it, I think we need to pray for them and not against others, asking God to preserve the saints and lead them towards perfection, harboring no grudge or resentment towards those who may oppose us or even abuse us -- but praying also for them.
Luke 6:28 Bless them that curse you, and pray for them which despitefully use you.
Ha, don't pray against them, pray for them. Ask God for something good. So I pray for God to preserve the saints and to bless those who may oppose me, hoping they will accept that blessing. If they do, I too have been blessed.
Matthew 5:11 Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake.
Or is what we learn in church supposed to be supported and encouraged?
I used to teach our faith...little good it did if it was not seconded at home.
It would be better if parents seconded things at home, but do not despair. They may grow up wild and crazy; but perhaps one day, when they fall onto hard times as the Prodigal Son did, they will remember things you told them and say, "I wonder if that was right. What I did didn't work too well." The little seeds sown may lie dormant for a while before they get enough water to sprout. The Prodigal Son was not in his right senses. He didn't know what he was doing; he didn't even know who he was.
Luke 15:17 And when he came to himself, he said, How many hired servants of my father's have bread enough and to spare, and I perish with hunger!
Then came the trek back, and his father had faith he would be coming back. Of course, he would come back, sooner or later. Where else could he go after he fell into deep despair? Why do I say his father was sure he'd come back?
"But when he was yet a great way off, his father saw him, and had compassion, and ran, and fell on his neck, and kissed him." Some people have to sink very low before they're willing to admit they have nowhere else to go. Notice too that the father didn't argue with his son when he wanted to leave. If the son wanted to do things his way, he could go and learn the errors of his way. Sooner or later, he would "come to himself" and remember who he was.
Peter didn't take that long.
John 6:68 Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life.
Therefore I wouldn't think you failed when trying to teach children the right way. Sometimes it takes time. Some of the work we do isn't finished until after we die. We could be in our graves (or at least our bodies) before the work we started gets finished. The people who were willing to die for Jesus did great works as witnesses for the kingdom.
Revelation 14:13 And I heard a voice from heaven saying unto me, Write, Blessed are the dead which die in the Lord from henceforth: Yea, saith the Spirit, that they may rest from their labours; and their works do follow them.
I wandered off for a while. Later, when I was less rebellious, I remembered things that people had told me a child -- things that helped me years after those people had died. I am sure God will reward them for it. I feel confident that your efforts also some day will bear fruit.
