I think that verse actually says, "he who endures tot he end shall be saved".
I was trying to explain the difference between genuine Christians and false professors. I know David committed adultery before he was saved, then he was very remorseful and he never committed any more serious sins. I'm not sure about when Abraham committed his, before or after but I'm almost certain that it was before.
But he who endures to the end shall be saved. Matthew 24:13
I don't believe that a true Christian who has the Holy Spirit indwelling them is capable of committing adultery or any other serious sin.
- The Life of Jesus within us, desires to express His righteousness and holiness, and lead us in the way of love.
- The sin within our flesh desires to express itself through unrighteousness.
Our choice is be a slave to sin by obeying the sin in our flesh, or be a slave to righteousness, by obeying the Spirit of Christ within us.
Only Christians who have obeyed the Gospel, have this choice, in which they have a new nature that is compatible with righteousness and holiness, able to contain the Holy Spirit and be led by the Spirit, having dominion over sin that dwells in our physical body.
Everyone else is a slave to sin.
16 Do you not know that to whom you present yourselves slaves to obey, you are that one’s slaves whom you obey, whether of sin leading to death, or of obedience leading to righteousness? 17 But God be thanked that though you were slaves of sin, yet you obeyed from the heart that form of doctrine to which you were delivered. 18 And having been set free from sin, you became slaves of righteousness. 19 I speak in human terms because of the weakness of your flesh. For just as you presented your members as slaves of uncleanness, and of lawlessness leading to more lawlessness, so now present your members as slaves of righteousness for holiness. Romans 6:16-19
Do you not know that to whom you present yourselves slaves to obey, you are that one’s slaves whom you obey:
- whether of sin leading to death,
- or of obedience leading to righteousness?
Paul wrote these words to Christians, who have the ability to walk in obedience and present their members as slaves to righteousness.
