Before starting class I just asked if anyone needed lotion as I stood with the bottle at the front of the class. As they said I do I walked around and gave all who needed a squirt.
Then as I put the lotion away I asked who could tell me as we find principles in the scripture block (Section 93 is where I was) what we are going to try and do. Just like we apply lotion, we "Apply it to our Lives".
Simple but whenever they ask for lotion we all remember the that Object Lesson. This can be used with any lesson really.
