What have you filled your tank with? Worry and fear will manifest in different ways. When you fill your tank with good thoughts then goodness will manifest. What you fill your tank with is what will manifest in your life. Life is a spiritual walk. When you are filled in the spirit then your life will manifest spiritual fruits. Fruits are to be enjoyed by the giver and the receiver. When you are filled with love then you feel loved and will be loving. This is a principle of the Kingdom. All authority is given to you from heaven, now go and do. When Jesus left the earth He gave His disciples authority to do many things. He asked them to preach the gospel, heal the sick, and rule on earth. All we have to do now is exercise this authority. Only authority that is exercised will produce results. You express this in word and deed. Imagine what this means when you know that you are living under His command. He will give you the words and the thoughts that will turn a situation around. The devil sows discord. Christ sows accord. There is no greater commission than the great commission.
