Work it out!
Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling. Philippians 2:12
This verse emphasizes that salvation is not something that should be taken for granted as the modern doctrines tend to encourage.
What Paul said here compliments what our LORD and Saviour Jesus Christ said when He said, "... but he that endureth to the end shall be saved". Matthew 10:22.
We are not saved by our works but our works takes us to the end victorious.
It's not by our works are we saved but by the sacrificial death of our Saviour. But if we do not have works then we certainly are not saved.
No one gets into heaven with dead faith.
Even so faith, if it hath not works, is dead, being alone.  Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works.  Thou believest that there is one God; thou doest well: the devils also believe, and tremble.  But wilt thou know, O vain man, that faith without works is dead?  Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar?  Seest thou how faith wrought with his works, and by works was faith made perfect?  And the scripture was fulfilled which saith, Abraham believed God, and it was imputed unto him for righteousness: and he was called the Friend of God.  Ye see then how that by works a man is justified, and not by faith only.  Likewise also was not Rahab the harlot justified by works, when she had received the messengers, and had sent them out another way?  For as the body without the spirit is dead, so faith without works is dead also. James 2:17-26
