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:
It was God that saved us and not we ourselves. I thank Him for having come and sought me out loving me when I did not love Him. 1John 4:19. He loved me while I was still a sinner. Romans 5:8. He saved me by His grace. Ephesians 2:8-9.
Now I have another promise of His grace. Not only did He save me but He will finish what He started. He is not only the Author but the Finisher of our faith. Hebrews 12:2.
Paul was confident that God would finish what He started in us. He will perform it until the day of Jesus Christ. What a wonderful promise. Your salvation is not in doubt if you are truly born again.
Not only that He is at work in you. The Holy Spirit is convicting you of sin. He is placing desires in you to serve and honor Him. Philippians 2:13. He is disciplining you when you get off track and do your own thing. Hebrews 12:8.
He is using everything that happens in your life to conform you to the image of His Son. Romans 8:28-29. You still have a lot to learn. He is still at work in a big way. He will be working all the time.
As you read the Scriptures you will learn how to please Him. You will want to please Him. As you hear the Word of God preached the Holy Spirit will work in your life to draw you closer and closer to Him. He will use every circumstance, every message, every thought, every prayer, every bit of Scripture you read to grow you.
Some of the experiences will not be pleasant. Some of the experiences will be to show you what you are doing is not pleasing to Him. But the wonderful promise is that you can know that He will finish what He started in you!
