The nature versus nurture argument has raged on for centuries. Here we see nature represented in that they all resemble their father. But nothing replaces nurture -- observe how the son looks at his father. I am convinced that the trust bond we witness in this video will have a lasting impact on the sons.
I pray all fathers and sons would know such trust and love. And for those who did not have such a father. I pray they will encounter the eternal and endless love of the Heavenly Father.
