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
Remain faithful to the purpose of God until the very end no matter how hard this world becomes. Jesus uses every good thing, every relapse, every failure, every mistake, every sacrifice, every service to others, and even every confusion we encounter on earth for good purposes. Seek His purpose of forgiveness, love, mercy, and wisdom every day. You will be a better person for having lived life that way.
We will leave this earth behind for heaven one day. Oh what rejoicing there will be in His loving arms. That purpose in our lives is enough to sustain us through the hard times.
