Reading this scripture above lets you know how powerful and creative words can be. With your choice of words, you can bring yourself more of life or more of death. It’s therefore important that you’re careful not to speak of yourself in a way that contradicts the Word of God in your life. It’s quite easy to get caught up with the negative language of the world: people, young and old alike, easily talk fear, lack, defeat, and failure. They see nothing wrong with it because it’s second nature to them. However, as God’s child, you shouldn’t imbibe such culture or talk because you’re not of this world. Your language, therefore, must be different.
When a Christian talks negatively, it rubs off on his spirit, contradicts the work of God in his life and affects his spirit. This is why some Christians who claim to know the Word of faith find it difficult to produce supernatural results in their lives. Their spirits have been loaded with the wrong stuff which must be removed through the knowledge of God’s Word. As you study and meditate on the Word, the circumstances of your life are altered to conform to the realities of God’s Word. The more you imbibe His Word, the more you’re transformed from glory to glory, with the Word building in you a positive mentality (2 Corinthians 3:18).
If you’re a student in the university or college, for example, no matter what task or project that’s set before you, learn to say “I can do this through Christ!” That’s what Apostle Paul meant when he said, “I can do all things through Christ who strengthens me” (Philippians 4:13). Recognize that you’re sufficient with God’s sufficiency, and as a result, you can do all things. Eliminate all forms of negativism and pessimism from your speech and vocab. Train yourself through God’s Word to see only boundless possibilities, and have the “I can do "mentality and talking".
