They must endure their torture stake just as Jesus did.
It's the struggle between serving God and not serving him. To serve God requires that we put away the works of the flesh, seek Gods righteousness and do his will until we die. Only if we do will we gain salvation.
"...God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth: Whereunto he called you by our gospel, to the obtaining of the glory of our Lord Jesus Christ. Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle."
(2 Thessalonians 2:13-15)
"Remember, therefore, what you have received and heard; hold it fast, and repent..."
(Revelation 3:3)
"Therefore, since we have a great high priest who has ascended into heaven, Jesus the Son of God, let us hold firmly to the faith we profess."
(Hebrews 4:14)
"Let us hold unswervingly to the hope we profess, for he who promised is faithful."
(Hebrews 10:23)
Keep your faith in Jesus because your deeds won't be good enough. Repent from your sins. And if you sin. Remember what the Apostle John said:
"My dear children, I write this to you so that you will not sin. But if anybody does sin, we have an advocate with the Father--Jesus Christ, the Righteous One."
1 John 2:1)
