Titus 3

For we ourselves were also once foolish, disobedient, deceived, serving various lusts and pleasures, living in malice and envy, hateful and hating one another.  But when the kindness and the love of God our Savior toward man appeared vv.3-4

Read chapter 3
Oh we must never forget how foolish we once were!  Let pride never get to us that we are better than others.  For before we knew the Lord as our Savior we were without wisdom, rebellious, deceived, giving in to lusts of the body and mind, doing what was good in our own eyes.  Let us remember where we once were before we act or respond negatively towards others.  Bible teacher Nathan Johnson says, "Our attitude towards others should be motivated from a realistic outlook on ourselves."  
And what was it that turned us from those things?  God's kindness and love!  It was nothing we did on ourselves to pull us out of the mess we were living in (and what still pulls us out of the mess we get ourselves in).  

“Love toward man” is the Greek word “philanthropia,” from which we get our word “philanthropy.”  It basically means a love (philos) of mankind (anthropos).  We need to understand that God loves humanity.  There is no other explanation for why He has allowed us to continue in spite of all the wickedness and perversion we have brought to this world.  God loves humanity, and it is His love that preserves us.  (N. Johnson)

Think back to when you were foolish and what was it that made a change in your life?  How do you see people in your life today with some of those same times of foolishness you once had and how do you respond?  Sometimes I respond worse to people I see my old self in so much, I need to be reminded of what got me out of that pit and show and respond that way to others.
