And I am sure of this, that he who began a good work in you will bring it to completion at the day of Jesus Christ.
Philippians 1:6 ESV
Take heart Christian, for the One who sustains us to the very end has no need for our weak strength. God has immeasurable power. The One who watches over us has promised that those who He begins a good work, will bring it to completion. Praise God that He does not lie.
In our own strength we can do nothing. It is not our own efforts that keeps us in the favour and presence of God. No, it is God's grace. God's sovereign grace saves a man and keeps him saved until the day of Jesus Christ.
Now, with His power and His grace, let us live unto God in accordance to His Word.
