Thank you for your question. When there is a possibility of danger, it is logical to have a level of precaution in order to maintain a safe distance from that danger. A person avoids walking along the ledge of a cliff or steep fall, tests the stability of an old bridge before walking on it, and stays away from war torn areas. So too when it comes to the bounds of God, it is only logical that when a person honestly doubts whether they are going to overstep those bounds that they take a level of precaution and don't walk on the ledge. So, for example, if a person thinks that if they attend a gathering of a certain group of friends, they will end up sinning, then it is better to avoid that gathering.
May you always be successful
