If God has set you free from something, then don’t hang around with the crowd that you did before. It only takes one person to lead you astray. That is how we allow satan to defeat us.
Jesus paid an agonizing, precious price for our sins so that we may have the liberty from our sins. Don’t let anyone tell you that doing something just once is okay. That is a lie from satan.
I have read and heard many testimonies from people who said that Jesus had set them free from alcohol, tobacco, drugs, and pornography, but they took just one drink, smoked one cigarette, shot the drug into their arms, went to one adult chat room, and were hooked worse than before.
When you are tempted to do these things that you did before Jesus set you free, then run to Jesus as fast as you can and ask Him to give you the strength to say no. He Loves you and is waiting for you with outstretched arms.
