Perseverance of the saints

He who began a good work in you will carry it on to completion.

My sheep listen to My voice; I know them, and they follow Me. I give them eternal life, and they will never perish. No one can snatch them out of My hand. My Father who has given them to Me is greater than all. No one can snatch them out of My Father’s hand.
John 10:27–29

being confident of this, that He who began a good work in you will carry it on to completion until the day of Christ Jesus.
Philippians 1:6

Who shall separate us from the love of Christ? Shall trouble or distress or persecution or famine or nakedness or danger or sword? As it is written: “For Your sake we face death all day long; we are considered as sheep to be slaughtered.” No, in all these things we are more than conquerors through Him who loved us. For I am convinced that neither death nor life, neither angels nor principalities, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.
Romans 8:35–39

Blessed be the God and Father of our Lord Jesus Christ! By His great mercy He has given us new birth into a living hope through the resurrection of Jesus Christ from the dead, and into an inheritance that is imperishable, undefiled, and unfading, reserved in heaven for you, who through faith are shielded by God’s power for the salvation that is ready to be revealed in the last time.
1 Peter 1:3–5

Now to Him who is able to keep you from stumbling and to present you unblemished in His glorious presence, with great joy— to the only God our Savior be glory, majesty, dominion, and authority through Jesus Christ our Lord before all time, and now, and for all eternity. Amen.
Jude 1:24–25
