Psalm 30:6 says this:
6 As for me, in my prosperity I said, I shall never be moved.
"Prosperity" here also means "ease". This psalmist was saying that when things were going well for him, then he had all the confidence in the world! We can all fall into that attitude that nothing could ever touch us, but if we are not preparing ourselves for the fight of faith, then the enemy will be able to trip us up! Preparation time is NEVER wasted time! How should we prepare? Look at Joshua 1:8:
8 This Book of the Law shall not depart out of your mouth, but you shall meditate on it day and night, that you may observe and do according to all that is written in it. For then you shall make your way prosperous, and then you shall deal wisely and have good success. AMP
Notice that WE are to make OUR way prosperous! How? By meditating on the Word of God so that we can understand it and then go DO it! Also by treating the Word of God as our vital necessity and our "necessary food" (Job 23:12)! The Word of God will give us understanding and will produce faith (Romans 10:17) and the Holy Spirit will give us the boldness to carry it out! (Notice in Acts 2 how Peter, who just a short time before denied Jesus 3 times, was now preaching the Gospel to thousands with boldness! Be filled with the Spirit and YOU can have that same boldness to obey God!) THEN we will be ready to NEVER be moved! AMEN! Here is Hillsong with another older song called "To The Ends Of The Earth":
Shalom in Him!
