Past

An inspiring point from Oswald Chambers:
"Never be afraid when God brings back your past. Let your memory have its way with you. It is a minister of God bringing its rebuke and sorrow to you. God with turn what might have been into a wonderful lesson of growth for the future."

Good things

Finally, brethren, whatever things are true, whatever things are noble, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report, if there is any virtue and if there is anything praiseworthy—meditate on these things. The things which you learned and received and heard and saw in me, these do, and the God of peace will be with you. Philippians 4:8-9

Points to remember:

1. Instead of thinking about negative thoughts of life, Paul here suggested us to keep our mind mediating on things that are true, noble, just, pure, lovely, of good report, virtue and praiseworthy. As time goes by, we will learn these good things, which are from the Father of lights according to James 1:17.
   
2. Learning, receiving, hearing and seeing things from Paul are by means enough, we have to DO these things.
3. The God of peace will be with you, whenever we practise these good things.
