Philippians 1:3-6

I thank my God every time I remember you. In all my prayers for all of you, I always pray with joy because of your partnership in the gospel from the first day until now, 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. 

I thank my God every time I remember you 
Romans 1:8  First, I thank my God through Jesus Christ for all of you, because your faith is being reported all over the world.

In all my prayers for all of you, I always pray with joy 
Romans 1:9-10  God, whom I serve in my spirit in preaching the gospel of his Son, is my witness how constantly I remember you in my prayers at all times; and I pray that now at last by God's will the way may be opened for me to come to you.

because of your partnership in the gospel

Philippians 4:15-16  Moreover, as you Philippians know, in the early days of your acquaintance with the gospel, when I set out from Macedonia, not one church shared with me in the matter of giving and receiving, except you only; for even when I was in Thessalonica, you sent me aid more than once when I was in need.

from the first day until now 
See Acts 16:12-40

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 1:9-11  And this is my prayer: that your love may abound more and more in knowledge and depth of insight, so that you may be able to discern what is best and may be pure and blameless for the day of Christ, filled with the fruit of righteousness that comes through Jesus Christ--to the glory and praise of God.
1 Corinthians 1:8-9  He will also keep you firm to the end, so that you will be blameless on the day of our Lord Jesus Christ. God is faithful, who has called you into fellowship with his Son, Jesus Christ our Lord.
