Hmm, God only knows the heart of man. God is a better judge than me yet the scripture is very clear, when we are saved, we are saved for eternity. Since a saved is still in his flesh, he had something to worry. Flesh is against the Spirit and since we are still here in the earth, we have an adversary, the Devil tempting us to do it. But you need to know that temptation itself is not a sin. It is giving in that becomes sin. As for the question granting after 10 years he steal back is he steal saved? Again, the his standing with God is righteous not because what he had done but because of what Christ done. What God see's is not our self-righteousness but God's righteousness by faith so that man is still save. His bad deeds, however, looses him his rewards in heaven during the Judgement Day of Christ.
This judgement is not about losing or gaining of salvation but rather obtaining or losing of rewards...in the form of Crowns

crown of life, which the Lord hath promised to them that love him.

crown of righteousness, which the Lord, the righteous judge, shall give me at that day: and not to me only, but unto all them also that love his appearing.
