In spite of the fact that most of our life circumstances are beyond our control, we are all still tempted to fret and complain about things that cannot be changed. Of course they cause distress. They certainly put us at a disadvantage in certain contexts. They mustn't be allowed to define or defeat us.
The people who do best with life move beyond the temptation to whine and feel sorry for themselves. They face their disappointments and move beyond them. They acknowledge life's bad breaks and look for ways to turn them into growth moments. They work from a half-full rather than half-empty glass mindset.
These people have a different attitude than the defeatist and whiner. They have found a way to make lemonade from their lemons.
There is a section in John Baillie's "A Diary of Private Prayer" that reads...
Teach me, O God, so to use all the circumstances of my life today that they may bring forth in me the fruits of holiness rather than the fruits of sin.
Let me use disappointment as material for patience;
Let me use success as material for thankfulness;
Let me use suspense as material for perseverance;
Let me use danger as material for courage;
Let me use reproach as material for longsuffering;
Let me use praise as material for humility;
Let me use pleasures as material for temperance;
Let me use pains as material for endurance.
Your attitude today will make all the difference in everything that matters.
Since you have been raised to new life with Christ, set your sights on the realities of heaven, where Christ sits in the place of honor at God’s right hand. Think about the things of heaven, not the things of earth. For you died to this life, and your real life is hidden with Christ in God. And when Christ, who is your life, is revealed to the whole world, you will share in all his glory (Colossians 3:1-4 NLT).
