Life shrinks or expands in proportion to one's courage

How often is it we doing that something that is wrong.  We even know it's wrong and we still do it!  Temptation gets the best and we just can't help give in.  We always tell ourselves. "just one more time, this will be the last".
We fool ourselves everyday.
I have concluded not only do I give into temptation much to often but I do with awful intentions!  I truly think I can trick God!  I have no idea why I do but I do!  I say to myself what does it matter everyone else does it or it's ok I won't do it tomorrow .
I often thought, if I question myself about doing things and whether they are right or wrong!  If I have think about it it's wrong.  Now to hold myself accountable.
