I have been avoiding a jehovahs witness friend for 3 weeks now when she knocks on the door I pretend im not home how should I tell her I have different beliefs?? Please pray that I find a way to tell her so I can stop avoiding her it makes me feel so bad inside.

Get some Christian tracks and literature so when she start talking about her believe, or gives you some of their literature you give her yours. After she leaves tear the ones she gave you and throw it away. Read the bible and get acquainted with some good verses you can use when she comes at you with her bible. Or come right out and tell her you respect her believe but you already have yours and expect her to respect yours. If she doesn't, then you know she is not your friend for she is not respecting you, so let her know how you feel. Honesty and truth are best always.
Lord give this person the courage to know beyond any doubt that you are their Savior. Give them strength to confront those that come at them trying to destroy their believe in you with wisdom, boldness, truth, and love. In Jesus name I pray amen.

Thank you so much helped me a whole lot

Yes,is good for us to be wise when people come to us and tell bad teachings. Few days ago,2 people came to my home and called : "Hello?" First did not know what they need to talk to,what they want.I was in the kitchen,and eating.And I ask to the Lord what should I do?And I understand that to not go out and talk with them.After that,I was thinking they must be from Jehovahs witnesses.

Dear Lord,please lead and help them to speak Your words in this kind of situation.We need Your guidance in our lives.
You are the King of kings and Your Name is Wonderful.
Thank You my Lord.

If she is a neighbor, take the advice I gave you before about the Christian literature, and confront her with kind words for you don't need to make her your enemy or anyone else. All you need is for her to see your strong faith in the Lord, and that you expect respect from her just as you give her. Then pray for God to open her spiritual eyes to see the truth of that erroneous teaching. Let God do the work in her for we can't force anyone to believe our way. We can show them the truth which is in the Holy Word and leave the rest to God. That's why it's good to always have some good Christian literature at hand for cases like this. My prayers are with you.
Lord make this person bold to stand up for their faith and show your love and kindness to others of a different faith without insulting them, or being afraid of them. For we win others to you by letting Jesus' love shine within us toward them. We are the light of the world, and this is a good opportunity to demonstrate it. In Jesus name I pray, amen.

We must be wise and guided by the Lord when we talk with people especially when we talk with Jehovahs witnesses. Why is that?I tell you from my experience.Once use to talk with them and because not was Lord's will,I was attacked by demons and I was so sad after that.Yes,our Lord is our Teacher too but it's better when we are guided by the Lord.
Only Lord knows what it is in them hearts and in all the hearts.Who will seek sincerely the Truth,surely will find the Truth.Today is so many teachings which are poison for the soul.Therefore is very important to read and to understand what the Lord want to tell in the Bible

Thank you chris I agree with you so many teachings today and some are false
