Hi Wilberforce, If you are a Christian the one with the blood may signify the blood of Jesus which you will need in order to do some of the things God will ask you to do instead of in your own strength. Your muscles are your own strength and God is telling you that you need to rely on Him and His blood. The finished work on the cross.
To accomplish anything in life and to open door of opportunities we need keys. God will give you small keys or clues, or ideas and if you follow through with what He is showing you then you will get the bigger key which will bring the major breakthrough.
Do not discount the small things. This is what God is paying attention to. One step at a time.
