Phil. 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.
Isa. 55:11 so is my word that goes out from my mouth:
It will not return to me empty,
but will accomplish what I desire
and achieve the purpose for which I sent it.
Isn't it relieving to know God uses us to accomplish his purposes? We may think we are in control of our actions, and we may go through the day without consulting with God regarding decisions, but God is in charge. God has the ultimate plan, which involves those of us who have accepted Him as Savior. Philippians 1:6 states we can be confident that God will finish the good work He has started in you. Confident... not "if we complete our to-do list" nor "if we live until we are 95"... We are to be confident God will complete the work in which He created us.
On top of this, Isaiah 55:11 reminds us God will accomplish what He desires and achieve the purpose for which he sent it. His desire and purpose is for all to follow Him, accept Him as Savior, and glorify Him. No matter what we chose to do or not to do, God's purposes will prevail. Be confident of this.
