Proverbs 4:23 (NLT) Guard your heart above all else, for it determines the course of your life.
Life is a gift. A broken heart can steal your life. The Bible tells us to guard our heart. It even teaches us how to do it (Prov. 4:20-23). However, I believe that a New Testament believer has access to something more than just a protected heart. I believe we can have a powerful heart. God wants us to flow in wisdom, knowledge, and joy. He wants us to have a heart that not only gives life, but one that provides an above average life.
If you are born-again, the Holy Spirit is inside your heart (2 Cor. 1:22). We need to take advantage of this. The Bible teaches us a way to do it. It says in John 6:29, "This is the only work God wants from you: Believe in the one he has sent." This is all we have to do; believe in Jesus. When we believe in Jesus, we can tap into that power He has placed inside us. The more we believe---the more power is released.
If you want to believe in Jesus, get to know Him personally. You can study His word, which is a good place to start, but to really get to know Him, you have to see Him. He is always with you. The Bible says in Matthew 9:28-29, "They [the blind men] went right into the house where he was staying, and Jesus asked them, "Do you believe I can make you see?" "Yes, Lord," they told him, "we do." Then he touched their eyes and said, "Because of your faith, it will happen."
Just as the blind man believes and then sees, look for Jesus in every moment. You will see Him; you will believe even more in Jesus and experience the greater life.
Why just keep what you have, when you can have so much more.
