2 Timothy 2:22 Flee also youthful lusts; but pursue righteousness, faith, love, peace with those who call on the Lord out of a pure heart.
Do you like to squish things through your fingers? It may be nice to squish purpose made things but what about something gross?
Getting carried away with your desires sometimes leads to you getting something gross on your hands – and that is not just the physical things we play with but spiritual matters too.
Trying to avoid bad things does not always work so staying away from the things that can get us involved with those bad things can help us to avoid them in the first place.
Some friends will encourage you to do good whilst some will encourage you to do bad – think about it.
