His word is in my heart like a fire

Jeremiah 20:7-18
You deceived^[a] me, Lord, and I was deceived^[b]; you overpowered me and prevailed. I am ridiculed all day long; everyone mocks me.
His word is in my heart like a fire, a fire shut up in my bones
But the Lord is with me like a mighty warrior; so my persecutors will stumble and not prevail
Sing to the Lord! Give praise to the Lord! He rescues the life of the needy     from the hands of the wicked.
Why did I ever come out of the womb to see trouble and sorrow and to end my days in shame?
Why?
Jeremiah was distressed under his circumstance, when he spoke the words of the Lord, people mocked him, his friends keep away from him and even planed to kill him.
Jeremiah was complain to the Lord for his situation, why he was born and saw these trouble and sorrow all his life.
But Jeremiah still praised the Lord, He is his mighty warrior, He rescues the life of the needy from the hands of the wicked.
To be a prophet of the Lord is doing and speaking the words of the Lord, wicked people don't like to hear it, even hate it, so the dangers are around them. But the Lord will protect us. Speak what the Lord said for our life is in God's hands, do not afraid but with wisdom to serve the Lord and needy people.
God's word likes fire in my heart is the feeling in Jeremiah, I believed when God's word comes to me, it will be like fire in my heart also. It will urge me go forward.
How?
Do what I can do, Say what I should say, Love whom I can love. Do not worry about it, and be still to listen the word of the Lord.
