Then God said... and there was.
God's word is powerful. In the story of Creation, for six days God spoke and the world was created. He didn't need to hire contractors, landscapers, or scientists and ask them to put it all together. He simply spoke and it came to be. When God said it, it was!
God has given us His word as a manual for life. Psalm 119:105 says that His word is a lamp for our feet and a light to help us to see our path. It helps us to see the way in which we should walk so that we don't get lost and we don't stumble.
The word of God is also a powerful weapon. When we are faced with temptation or when we are under attack from the enemy, our best defense, our best plan for overcoming, is to use the word of God. But, for it to be truly effective, it must be in our hearts. We need to read it and allow it to live in us. We need to do what it says. And, we need to cling to it.
Jesus used the parable of the sower (Luke 8:1-15) to explain that the word of God must take root in us so that the Kingdom of God can grow. The key for us here is allowing it to take root. When we simply hear the word, but don't allow it to take root in our hearts, the enemy can come in and just take it from us. If the word is not deeply rooted in our hearts, it also makes it easy for temptation to cause us to fall away. If we don't cling to His word, the cares and pleasures of life will try to crowd it out and keep us from maturing in our faith. But, when we hear God's word and cling to it, when we allow it to take root in us, our lives can be used to produce a great harvest for God's Kingdom.
Scripture tells us that God's word is alive and powerful (Hebrews 4:12). He has provided it to us so that we can grow in our faith, stand firm when adversity comes, and be molded more and more into His image.
