Likewise you also, reckon yourselves to be dead indeed to sin, but alive to God in Christ Jesus our Lord

Romans 6:9-11
Death no longer has dominion over Him. 10 For the death that He died, He died to sin once for all; but the life that He lives, He lives to God. 11 Likewise you also, reckon yourselves to be dead indeed to sin, but alive to God in Christ Jesus our Lord.

When Yshua rose from the dead, He showed to all that He had conquered death. He did not sin, but had the sins placed upon Him, which led Him to the cross. He had lived His life to God. We too can follow Him in giving up our lives of sin and live according to God. To do this, we must be alive in Jesus, that is letting the Holy Spirit guide us.
