Worthy is The Lamb
Jesus Christ is the lamb and the perfect atonement for sin. He was bruised for our transgression. He was innocent, but He was punished. God doesn't tolerate sin. He is pure and Holy and He will destroy sin from off the face of the earth. No man can enter heaven as a sinner. No man can come unto His presence as a sinner. For all have sinned and fallen short of the glory of God. But, with we can come before His presence in songs of praise and petitions of prayer. We must first repent of sin and accept Jesus Christ into our heart. Only then can we obtain the promises as adopted sons and daughters. He is forgiving and He sees us through the blood of Jesus Christ which has washed away all our sin. How glorious and marvelous His works. That is the joy and beauty of salvation which is a free gift for all of humanity.
Revelation 5:12
"Saying with a loud voice, worthy is the Lamb that was slain to receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing."
