Negative thoughts seem to strike everyone, but when you’re focused on more positive, God-approved things, the not so positive thoughts tend to become non-existent.
The most important way of all for help in changing one’s focus to "happier" thoughts is through prayer. It’s really sad how often we have to be reminded of this. Just taking a few moments to talk things over with The Lord, no matter how trivial they may seem, can make a huge difference in how we handle things in our day-to-day lives. In the old gospel hymnal, "What A Friend," there’s a portion of the song that says, "Can we find a friend so faithful, who will all our sorrows share? Jesus knows our every weakness, take it to The Lord in prayer." He knows what we’re going through, even before we’re going through it, so wouldn’t it make sense to take it to Him?
"Come unto me, all ye that labour and are heavy laden, and I will give you rest." (Matthew 11:28)
Another way to change our focus is through studying His Word. Anyone who thinks there’s nothing new to learn in the Bible needs to pick it up again. God’s Word is not a surface book. There are many lessons to learn, many "dark sayings" to consider, and many blessings to receive. We can’t blame anyone for our own lack of spiritual growth if we let this area of our faith/worship decline.
"Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth." (2 Timothy 2:15)
Beyond the spiritual, there are also new hobbies to try, new projects to start, new places to go. Anytime we feel our minds beginning to head down that negative-thinking road to nowhere, we should make ourselves stop right there and pray. If our Bibles aren’t handy, we could quote a favorite verse in our minds, or sing a line or two of an old, uplifting song. Whatever works, as long as it’s within godly reason, is worth trying.
"Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and there be be any praise, think on these things." (Philippians 4:8)
