David was a man who walked through trouble on a regular basis. His psalms express the struggles and disappointments he faced, yet in the end, he always turned his focus back to God. The key to his victorious attitude was his strong faith in the Lord.
David was confident in God's purpose. That's why he could say, "The Lord will accomplish what concerns me" (v. 8). The only way we can walk through trouble and not be defeated is by keeping our focus on the Lord and His purpose. He has promised to do a good work in our lives, but sometimes the only way He can complete it is in valleys of hardship.
He relied on the Lord's power. When troubles arise, we, too, can trust God to deliver us, but it may not be by escape. Sometimes He sustains us through the difficulty, walking with us every step of the way.
David believed the promises of God. Throughout these two verses, he repeatedly reminds himself what the Lord will do. We also need to have some specific promises from Scripture that will anchor us in times of trouble. The truths of the Bible are our most valuable possession when the storms of life assail us. Self-reliance or advice from others will never equal the help God's Word offers us.
God assumes responsibility for accomplishing what concerns you in times of trouble. Your job is to believe that He will fulfill His purpose, His power is adequate, and He'll keep every promise. When the trial has achieved His goal, He'll remove it. Until then, keep walking with your eyes on Him.
