TAKE RAHAB FOR INSTANCE: Rahab has come to be known as a prostitute. The Bible describes her as a harlot. Rahab was the owner of a business where many that traveled in caravans frequented. She heard the many exploits from the many travelers that stopped there of a God that parted the Red Sea and saved His people from imminent danger and destruction. This caught her attention. You see she lived among a people that did not worship the one and only true living God of Israel, but a moon goddess by the name of Ashtaroth. She decided to hide two spies who were running from soldiers that sought to kill them. She exercised her faith in believing that the God that saved His people from Pharaoh and the Egyptian army, could very well save her. She risked her very own life and the life of her family in lying to the soldiers that came shortly thereafter seeking the two spies. The spies promised to spare Rahab and her family after taking the city if she would mark her house by hanging a red cord out of the window. When the walls in the city of Jericho came crashing down, Rahab and her whole family were saved just as the Israelite spies had promised. Despite the immoral background of Rahab, she was used by God. She is now listed in the "Hall of Faith", and listed in the direct lineage of Jesus Christ. She became the wife of Salmon, the mother of Boaz, who married Ruth from whose son, Obed, Jessie the father of David came, through whose line Jesus was born. Yes, someone whom we as society would have thrown away was part of the very lineage of Jesus Christ Himself!
TAKE A LOOK AT SAUL FOR INSTANCE: Paul was taught by one of the most well-known teachers of the law, a Pharisee by the name of Gamaliel, who was admired by all of the Jewish leaders. Saul was noted for his hatred of Christians and believed the teachings of Jesus violated the Mosaic Law. For that reason, he aggressively came against anyone who followed the teachings of Jesus Christ. He received permission from the high priest to travel to Damascus for the distinct purpose of imprisoning those who followed Christ.
Most believers in Jesus Christ have heard the story of the Damascus road where Saul was blinded; knocked off of his horse and heard the voice of Jesus Christ. Saul was saved by Jesus Christ after he repented and his name was changed to Paul after his baptism.
Apostle Paul was not perfect, but he became one the greatest witnesses of Jesus Christ that ever lived by teaching, inspiring, growing and encouraging the early church. He went on to write much of the New Testament.
Now to make my point! We see the outer shell of a person and judge them in their here and now. We can't see past their faults, hang-ups, issues, habits and sin. You see God knows all endings from their beginnings. He looks past all of the fault and see our need of a loving and kind Savior that died to save us from such. God knew that man could not live a successful life here on earth from the practises of sin, so Jesus sent back another Comforter, the Holy Ghost to keep, lead, teach and guide us into the truth of all ways of righteousness.
Some of those very people that you have turned your nose up at or even looked at in a cross eye may very well be assigned to you. You may be the only Bible they will ever read. Many have been written off as useless, no good and never amounting to anything. Don't write them off, count them out and please don't give up on him/her. God can use anyone and we are His agents in the earth that will be used mightily by Him to reach them after their own personal conversion by Him!
God can clean up that woman or that man that is strung out on drugs; God can deliver that young lady who desires to live her life as a man; God can deliver that young man who desires to live his life as a woman; God can deliver that liar, that backbiter, that murderer; that gambler; so on and so on and create a battalion of soldiers that will tear down the enemies kingdom with the truth, way and life of Jesus Christ!
GOD CAN USE YOU for HIS GLORY!
