Concentrate on giving thanks for your blessings and you will begin to find a song of praise in your heart. If you concentrate on what you don't have and all the things that keep going wrong in your life, you will build worry and discontent in your heart. Melodies cannot spring forth from this kind of environment. We are commanded to speak psalms and hymns to one another in fellowship and to uplift and encourage each other. Surrounding yourself with positive people will rub that positive influence into your life. The company you keep and the environment where you plant yourself do have an impact on your joy and contentment. Therefore, make wise choices and be a positive influence on others as you concentrate on making melodies of praise in your heart to the Lord until it becomes second-nature and it no longer requires concentration.
