righteousness

What is required of us by God that we may enter the kingdom of heaven? Answer: We must be free of sin. We must be righteous. But we know none are righteous, no not one, so how is it possible. With man it's not possible, but with God all things are possible. That is why God the Son left His throne to live among man and gave Himself as a perfect and Holy sacrifice. How awesome is this! He invited us to live with Him forever and paid the price for our admission. All we have to do is have faith, believe and accept Jesus as our Lord and Savior. As a believer our sins are washed away with the blood of Christ and His righteousness is transferred to us as if we had lived sinless lives. Securing a place in His Kingdom forever. What could be any better than this; Having a God that loves so much that He suffered in our place. 
And this is the Gospel "... Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures: " 1 Corinthians 15:3-4
