There is an Irish tale that says there is a pot of gold at the end of the rainbow and there's the end, but where is the gold? Its right in front of you but you can't see it. No, I am not trying to confuse you, just to make a point; the lighthouse is gold to the seamen when the light is on. This little item could save their lives and that's worth more than any bar of gold anyone could dream up. Apart from the physical lighthouse, there is the light it shines forth; light to guide, to illuminate, to provide a safe haven of rest. I like what the apostle John has to say at the beginning of his book about light.
Joh 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
Joh 1:2 The same was in the beginning with God.
Joh 1:3 All things were made through him. Without him was not anything made that has been made.
Joh 1:4 In him was life, and the life was the light of men.
Joh 1:5 The light shines in the darkness, and the darkness hasn't overcome it.
Joh 1:6 There came a man, sent from God, whose name was John.
Joh 1:7 The same came as a witness, that he might testify about the light, that all might believe through him.
Joh 1:8 He was not the light, but was sent that he might testify about the light.
Joh 1:9 The true light that enlightens everyone was coming into the world.
Joh 1:10 He was in the world, and the world was made through him, and the world didn't recognize him.
Joh 1:11 He came to his own, and those who were his own didn't receive him.
Joh 1:12 But as many as received him, to them he gave the right to become God's children, to those who believe in his name:
Joh 1:13 who were born not of blood, nor of the will of the flesh, nor of the will of man, but of God.
Joh 1:14 The Word became flesh, and lived among us. We saw his glory, such glory as of the one and only Son of the Father, full of grace and truth.
Joh 1:15 John testified about him. He cried out, saying, "This was he of whom I said, 'He who comes after me has surpassed me, for he was before me.' "
Joh 1:16 From his fullness we all received grace upon grace.
Joh 1:17 For the law was given through Moses. Grace and truth came through Jesus Christ.
Joh 1:18 No one has seen God at any time. The one and only Son, who is in the bosom of the Father, he has declared him.
World English Bible
Jesus made light and life, became light and life and gives light and life to those who will see it. Not everyone can, but when illuminated with spiritual power, understanding and change is possible. This change is like being born all over again and with this new spiritual insight life becomes new. So, don't look for gold, rather, look for insight from Jesus, because HE is the message from the father and that message is really good news to those who see what HE IS SAYING.
