The most important thing for a christian is to forgive others

A Christian should has LOVE first. How can you forgive someone if you don't have LOVE. Love is the first and foremost. Jesus says how can you not love your neighbour but say you love God who you never seen. So LOVE is the uttermost in Christianity. Read the book of 1 John and you will see for yourself.

Anything that pertains to your personal relationship with God and Jesus is important. A forgiving attitude is only part of it. To humble ourselves before God is just as important. To learn to depend on God is just as important. Probably to learn how to communicate with God is the most important. God being able to share His wisdom with us is the key to everything else. God's wisdom will teach us how to put everything else together where we can have a good personal relationship with Him. The Bible tells us to "Seek you first the Kingdom of God". Only through a good working one on one relationship with God can we enter into His Kingdom.

I agree with your opinion. Yesterday I made a quarrel with one of my lead, now when I recall it, I feel I must be mad at the time, I thought he will still angry about my impolite today, but no, it seems that, he forgive me. I am so happy now.
