Philippians 1:6

Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ:

being confident of this very thing, that he who began a good work in you will complete it until the day of Jesus Christ.

being confident of this very thing, that he who began a good work in you will perfect it until the day of Jesus Christ:

having been confident of this very thing, that He who did begin in you a good work, will perform `it' till a day of Jesus Christ,

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.
