Jesus said in the Bible that everyone must give an account of every careless word spoken while on Earth on the Judgement Day lah!  So I shall be more careful of my comments lah!

Jesus didn't teach tit for tat but to turn the other cheek.  It has a very profound meaning which does not mean that if your colleague backstabs you by lying about you to your boss, you encourage him to tell one more lie about you.  Neither should you retaliate by lying about him to the boss.

And yes, we need to watch what we say....and do.  We all know that, we try but being sinners we will sin, however hard we try not to.  But it does not mean that we can go and sin and sin on purpose.  

As sinners, we have the nature and character of a sinner, and as long as we are in this flesh, we will continue to sin from time to time.  But we should go to God and ask for forgiveness in Jesus' name, and God WILL forgive us if we are sincere...we need not go on a guilt trip.  In Christ, our salvation is assured.
