We need to train our younger generation. It is so important for Christians to study the Old Testament and learn how God dealt with His people during the time that He was bringing up a nation in which to bring forth His Son and the New Covenant. We can read of good examples of faith, but we can also read where the older generation did not train the younger, and many times they were in bondage to other nations whom God raised up to punish them. Yes, we need to study the Old Testament today, for various and obvious reasons.
Judges 2: 7-10 “... And the people served the LORD all the days of Joshua, and all the days of the elders that outlived Joshua, who had seen all the great works of the LORD, that he did for Israel. And Joshua the son of Nun, the servant of the LORD, died, being an hundred and ten years old. And they buried him in the border of his inheritance in Timnathheres, in the mount of Ephraim, on the north side of the hill Gaash.
“And also all that generation were gathered unto their fathers: and there arose another generation after them, which knew not the LORD, nor yet the works which he had done for Israel.“
