Believe on Jesus now as your Saviour and you will have eternal life.
"All who received Him (Jesus), to those who believed in his name, he gave the right to become the children of God"
St. John 1:12
To be a child of God is to be adopted into God's family, know God as Father, and possess eternal life.
Receiving Jesus is believing he has saved you from your sins and has won for you, by his death for your sins, God's declaration that you are righteous in His sight.
