Rahab's story is found in Joshua 2 and 6
Rahab was a woman living on the fringe of society, working as a prostitute. We find her in the midst of rumors of war and allegations against the Israelites camped outside the city walls of Jericho. We all know the story of Joshua and his men marching around Jericho until the walls fell down, but another story happens during this time as well, inside those legendary walls. A woman is converted and her life is changed forever.
Rahab was indeed part of the lower class in Jericho, more likely an outcast amongst most of the city, save those who valued her services. She was a Canaanite which meant she likely worshiped idols and false gods. She did however hear the rumors of these Israelite people, how their God had saved them from certain death and rescued them from slavery in Egypt. I would assume that many of the townsfolk of Jericho believed these were fairy tale adventure stories for children, but Rahab believed they were true and she questioned what she believed her whole life. When two Israelite spies show up on her doorstep, she had a choice to make. She could turn them in to the king, be a hero and probably receive some monetary compensations for bring them in...OR, she could hide them from the kings army and help the plan of this foreign God she was so interested in. She decided to help them by hiding them on her rooftop among the drying grain. Rahab diverted the kings army and helped the men escape through a window in the city wall. Before they left she begged for amnesty for herself and her family. The spies agreed because of her kindness. Rahab and her family were spared and she believed in God all the more. After some time living in the city with the Jews who'd conquered it, she was married to a Jewish man named Salmon. Her life did an about face, turning her back on her past and focusing on her present and future. A life changed forever.
Have you ever faced a choice to follow God or to follow your own agenda? Rehab could have turned the men in and she would have been a hero, but she decided to follow God instead. She was rewarded greatly for her decision and was grafted into the family of God, first among the Gentiles to convert. If Rehab could chat with us today, she would tell us that life is an adventure, and every adventure requires faith in God. The courage to take healthy risks comes from trusting God and knowing He is in the adventure with you. She might also tell us it's not where you came from or what sin you've committed that matters, God is with you always waiting for you to reach out to Him for help and salvation.
The next time you have a tough decision to make, remember Rehab. She may have been a low class prostitute at one point, but the moment she believed in God and proceeded in faith, a new life was born in her. No matter what your situation (or your past), God is there with you too. Be encouraged, The bible tells us sin is all the same none bigger or smaller, and the delight of God's heart is to graft us into His family of saints. Salvation is free and available to anyone who seeks it. Jer 29 "For I know the plans I have for you, plans to prosper you and not to harm you..."
