There are many signs that God has left for us in the Bible that are meant to remind us of Him and Him of us. The Rainbow that appears in clouds is one such sign. It represents a covenant between God and Mankind and every living creature on the face of the planet, including the planet itself.
When God sees the Rainbow it reminds him and us that the waters will never again rise to destroy all flesh.
When I became a believer in Jesus, I noticed that mankind also put a sign on the earth representing a new covenant, but not with God. This sign that met my gaze everywhere I looked was the telephone pole. It was mans covenant with himself. This covenant represented the future of Technology, Communication and Science. It allowed man to speak with himself but not to God.
Daily as I looked across the landscape I saw crosses everywhere. It was as if the world had become a graveyard with millions of crosses. Each cross represents a person and their inevitable appointment with death because of their sins.
You need to realize that heaven is for perfect people and you are not perfect, therefore you cannot get in. But if you understand the Cross of Christ and look closely, you will see HIM on your cross, in your place having already paid the price for your sins by dying for you.
Then if you acknowledge that Jesus is Gods Son, that He died in your place for your sins, past, present and future, you will gain entrance into His Father’s Heaven.
