In looking at the symbols of the Arabs or darkish colored Asians. This indicates to me that these are Christians who are striving with a degree of sin, selfish ambitions or unbelieving (doubting) God. God is clearly showing you that he has put a very powerful ministry in your heart and given you the ability to prepare them to seek God and receive His help to restore their relationship with Him. God wants us to make our petitions known to Him.
