1 Peter 2:23-25New King James Version (NKJV)
23 who, when He was reviled, did not revile in return; when He suffered, He did not threaten, but committed Himself to Him who judges righteously; 24 who Himself bore our sins in His own body on the tree, that we, having died to sins, might live for righteousness—by whose stripes you were healed. 25 For you were like sheep going astray, but have now returned to the Shepherd and Overseer of your souls.
Having died to sins, means sin no longer has any death power over Christians. Christians are dead to sin. Christians live to righteousness.
Christ put away sin by the sacrifice of Himself, yet there remain people convinced their sins still have the second death power over them.
Well perhaps they do many sins and still have not been born of God, so they really are unsaved frauds, hypocrites, false brethren.
Hebrews 9:25-28New King James Version (NKJV)
25 not that He should offer Himself often, as the high priest enters the Most Holy Place every year with blood of another— 26 He then would have had to suffer often since the foundation of the world; but now, once at the end of the ages, He has appeared to put away sin by the sacrifice of Himself. 27 And as it is appointed for men to die once, but after this the judgment, 28 so Christ was offered once to bear the sins of many. To those who eagerly wait for Him He will appear a second time, apart from sin, for salvation.
For Christ's believers in Him, the sin problem has been put away as to regarding their salvation. They eagerly await His returning.
Sin is no longer any barrier between God and His people, though their sins be as scarlet, they shall be white as snow.
Hebrews 8:11-13New King James Version (NKJV)
11 None of them shall teach his neighbor, and none his brother, saying, ‘Know theLord,’ for all shall know Me, from the least of them to the greatest of them. 12 For I will be merciful to their unrighteousness, and their sins and their lawless deeds I will remember no more.”
13 In that He says, “A new covenant,” He has made the first obsolete. Now what is becoming obsolete and growing old is ready to vanish away.
