"Being confident of this very thing, that He who has begun a good work in you will complete it until the day of Jesus Christ." (Phillipians 1:6)
When we decide to give God all that we are, His work can be faithfully completed inside of us... if, we are faithful to Him until the day of Jesus Christ. And in order to remain faithful to Him, we need to live with a constant faith in action, with power and growth.
It's inconceivable for someone who says they are in Christ, to remain motionless in their communion with God and here lies the importance of devoting ourselves, renewing ourselves with the first works, because His work will be completed until the return of the Lord Jesus, if we remain in Him.
The Lord Jesus wants to perfect our relationship with Him every day... leading us to bear many fruits. He has been waiting for you to completely surrender your life to Him so He can finally fulfill His good work in you — He loves you so much! He wants to begin and complete His works in you... decide today, go and meet him with all your strength, you have nothing left to lose!
