John 15:1-5
“I am the true vine, and My Father is the gardener. He cuts off every branch in Me that bears no fruit, while every branch that does bear fruit He prunes so that it will be even more fruitful.
You are already clean because of the word I have spoken to you.
Remain in Me, and I will remain in you. No branch can bear fruit by itself; it must remain in the vine. Neither can you bear fruit unless you remain in Me.
I am the vine; you are the branches. If a man remains in Me and I in him, he will bear much fruit; apart from Me you can do nothing.”
Philippians 1:6
... 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.
1 Corinthians 1:8
He will keep you strong to the end, so that you will be blameless on the day of our Lord Jesus Christ.
2 Thessalonians 1:11
With this in mind, we constantly pray for you, that our God may count you worthy of His calling, and that by His power He may fulfill every good purpose of yours and every act prompted by your faith.
2 Thessalonians 3:3
But the Lord is faithful, and He will strengthen and protect you from the evil one.
