There are reasons for suffering that bring glory to God, so we are never to judge anyone who is going through a trial. Our part is simply to think no evil, to believe the best, and to pray. And, when something comes against us, instead of reacting we can see how to add degrees of glory for now and forever.
A carnal man enters a trial and self-destructs. He suffers because problems in his emotions have never been resolved, and he is angry at every other thing. The Spirit-filled man triumphs in a test, knowing that glory will be his reward. His emotions are kept by God's mind as he receives and responds to love and grace from the Father.
When pressures come to the Spirit-filled man, he can be very quiet. There is no need for tension. What good does it do to become upset? Has worry every delivered anyone? A relaxed man is one who rejoices in the face of temptation, who fellowships with Christ, and who rests in God's plan. He knows that God will provide what is necessary to go through the trial, and that makes it most precious.
