Some say that you cannot work your way into Heaven. This is true to a point, but it is important to know that you will not realize eternal life without works. The following reviews relevant scriptures on this topic.
By Grace, Through Faith, Unto Good Works
We are saved by the grace of God through faith unto good works.
Ephesians 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 9 Not of works, lest any man should boast. 10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
Faith Is Shown Through Works
Faith is demonstrated via good works. Without works there is no faith.
James 2:18 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. 19 Thou believest that there is one God; thou doest well: the devils also believe, and tremble. 20 But wilt thou know, O vain man, that faith without works is dead?
Keep the Commandments
Obtaining eternal life requires the keeping of the commandments.
Matthew 19:16 And, behold, one came and said unto him, Good Master, what good thing shall I do, that I may have eternal life? 17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
Chosen/Elect through Sanctification
Disciples are chosen to salvation through a process of sanctification of the Spirit.
2 Thessalonians 2:13 But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth: 14 Whereunto he called you by our gospel, to the obtaining of the glory of our Lord Jesus Christ.
This process requires the obedience of the disciple.
1 Peter 1:1 To the strangers scattered throughout Pontus, Galatia, Cappadocia, Asia, and Bithynia, 2 Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied.
Work Out Your Own Salvation
The process of sanctification of the Spirit is the working out of our salvation.
Philippians 2:12 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. 13 For it is God which worketh in you both to will and to do of his good pleasure.
Judged by Works
Christ will reward us according to our works.
Matthew 16:27 For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works.
We will ultimately become like Christ or not and will be judged by what we have worked to become.
Revelation 20:12 And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works.
Works are an indispensable element of the process of sanctification through which we become like Christ and learn to live the the kind of life that he lives, eternal life.
