For God is not unjust. He will not forget how hard you have worked for him and how you have shown your love to him by caring for other believers, as you still do. Our great desire is that you will keep on loving others as long as life lasts, in order to make certain that what you hope for will come true. Then you will not become spiritually dull and indifferent. Instead, you will follow the example of those who are going to inherit God’s promises because of their faith and endurance.
Hebrews 6:10-12 New Living Translation (NLT)
Who among us can say what God is doing? For that matter, we are not even qualified to testify of what He may be doing in our own lives. Often, we have already gone through a trial or received a blessing before we truly know what has happened to us. God did not send His Son to save us at our request. It was after God sent Jesus to give His life for our sin, we were asked to believe that He did this and elect to follow Him. It is God who is working through us according to His will, not our own.
Whatever we do for God, He will not forget. It was He who began the good work in us in the first place. It is His desire that we follow His commands to love and to serve. Our obedience, faith and endurance will be rewarded by an inheritance of His promises. It is only by God's grace that we can accomplish anything good.
And I am certain that God, who began the good work within you, will continue his work until it is finally finished on the day when Christ Jesus returns. Philippians 1:6 NLT
