Because of these studies on memory, I've wondered how responsible we are for what we do based on what we have seen. If a picture we don't even remember can influence a particular choice days later, was that choice made with free will? Or were we so influenced that free will did not apply?
I don't know, but I do know that we have a choice about what we look at in the first place. We can avoid looking at advertising, internet sites and movies that lead us into sin through what is portrayed. Avoiding sin means not putting ourselves in a position to see things that lead our minds and bodies astray (see Matthew 5:27-30).
For reflection: Where and when have I been deliberately looking at temptation? Where and when have I accidently been led into temptation? How can I avoid these?
Let us pray. Jesus, I am guilty of looking at things I shouldn't. Renew a clean heart and a right spirit within me. Do not look on my sins or take your Holy Spirit away from me. Instead, grant me a willing spirit to help me. (based on Psalm 51)
