Your actions determine your destiny. Your actions are the reason you are where you are where you are and they are the reason that you will be where you are in the future. If you've done nothing then you have nothing. Treat people well and you will be treated well. Spread love and you will be loved. Have good will towards others and others will have good will towards you. Do the opposite and you will have he opposite.
God made us so that what we do affects others and what others do affects us. This is how he made the universe. Do unto others as you would have others do unto you. There is a balance to the universe and the universe cannot exist without this balance. That's why whatever you do comes back to you. It may come back ten fold in a short time or it may not come back at all in the short run, but rest assured, in the end everything will balance out. While you may not experience the consequences of your actions immediately, you will experience them at some time in the future.
There is an energy that moves between us . It binds us together. Sometimes when you let go of conscience thought and really hone in on what the energy is doing, you can feel it guiding you. You can feel it moving through you. People call it by different names. We in the Christian community call it the Holy Spirit. It is our connection to God. It is our connection to each other. Let it move through you and listen to it and it will guide you to harmony and love. Harmony and love are the natural state of things.
