Psalm 78 1-8, God commands all generations to teach the testimony of Jacob.
Did Jesus keep this commandment? We, who believe Jesus was the Son of God, knows he was perfect. Therefore, we know he kept the commandment of His Father.
Why has the Church not made the connection that when Jesus taught the Parable of the lost son, he was keeping God's commandment to teach the testimony of Jacob.
To truly understand the depth of the Parable of the lost son, we need to understand, in depth, the testimony of Jacob.
The parable of the lost son is not simply a "neat" story showing us God's saving Grace and unconditional love.
The testimony of Jacob is the key to us understanding what a true relationship with God, Jehovah Jireh, is all about. The Church has not yet made this connection, because they do not understand the testimony of Jacob. If they don't understand it, they definitely aren't teaching it and are not keeping God's commandment of Psalm 78.
