The deceitfulness of oneself

Yesterday, I was renewing my membership at the community center. I noticed they had discount pricing for students. Out of curiosity, I asked them about that.

They replied that I had to be over 19 and going to school full time. It was at that point I was taking out my McMaster Student Card. I flipped the card around to see if it stated whether I am full time or part time.

For a brief moment, I was tempted to justify the student discount. After all, they cannot prove I am a part time or full time. I could convince them I am a full time student.

My justification is that I am only using the community center to swim. The regular price, $51/month, is too expensive to do that. Being a student, I can save at least $15.

Oh how frail and weak I am. Fill with sinful desires. How I am willing to sin for a mere 15 dollars.

I put my card away and told them to charge me the adult price.

13 Keep your servant also from willful sins;
may they not rule over me.
Then will I be blameless,
innocent of great transgression.

14 May the words of my mouth and the meditation of my heart
be pleasing in your sight,
O LORD, my Rock and my Redeemer. (Psalm 19:13-14)
