Paul encourages us to be "walking in love", and by that he means that we should endeavor to  live without "bitterness", and let anger be taken away from us, and  avoid slandering others. He entreats us to be kind and gracious in our every day dealings with others.

He reminds us that God our Father has been gracious to us.  So, too, we should treat others "graciously", with kindness.  In other words, as we are in Christ, as God as so graciously placed us, we should be like Christ in our daily life.

Considering, of course, that we are human, possessed with all the human failings, it is impossible to be "Christ-like", but we should attempt to be as He would have us be.

Even though, we should miss the mark (sin), God does not hold those sins against us, as we are justified of our sins, through the faith of our Lord, Jesus Christ..not our faith.

But, as we have so greatly benefited from His faith, we should make every effort to be worthy of this, by "walking in love"..paulnbob
