'NEVER'

The word 'never' is used to emphasize that something is absolute in its exclusion ... at no time, under any circumstance.

Therefore, a precious promise comforts those who know Christ as Lord ... for He hath said, I will NEVER leave thee, nor forsake thee. (Hebrews 13:5)

In a world of constant change, Jesus is our 'immutable' Savior ... the same yesterday and today and forever. (Hebrews 13:8)

The Son of God made sacred vows that cannot be broken ... 

He never loses sight of those who serve Him ... Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things I have commanded you. And remember, I am with you always, even to the end of the age. Amen. (Matthew 28:19-20)

He never abandons you once your life is surrendered ... I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh, I live by faith in the Son of God, who loved me and gave Himself for me. (Galatians 2:20)

He can never be taken from you ... For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come, nor height nor depth, nor any other created thing, shall be able to separate us from the love of God which is in Christ Jesus our Lord. (Romans 8:38-39)

He never leaves you to your own devices ... I will pray the Father, and He will give you another Counselor, that He may be with you forever: the Spirit of truth, whom the world cannot receive, for it does not see Him, neither does it know Him. But you know Him, for He lives with you, and will be in you. (John 14:16-17)

He will never cease preparing you for His kingdom ... He who has begun a good work in you will complete it until the day of Jesus Christ. (Philippians 1:6) 

Focus on those promises, dear believer.

The assurance of your salvation can be found in the word ... 'never'.
