To be a real worshiper to the Lord; Jeremiah 7:1-11

Jeremiah 7:1-11
This is what the Lord Almighty says: Reform your ways and your actions, and I will let you live in this place. Do not trust in deceptive words and say, "This is the temple of the Lord!" 
If you really change your ways and your actions and deal with each other justly, if you do not oppress the alien, the fatherless or the widow and do not shed innocent blood in this place, and if you do not follow other gods to your own harm, then I will let you live in this place for ever and ever.
Has this house which bears my Name, become a den of robbers to you? But I have been watching! declaring the Lord.
The people had a superstitious faith in the Temple. They though God would always protect Jerusalem as he had done because his Temple was there. They were wrong, God sends Jeremiah to stand at the Temple gate and tell them that God knows the difference between religious ritual and real religion. He sees all that goes on.
Why?
Because they do many things that God hates and did injustice things. So even Temple of God is there but God does not protect them. They worship the Lord by ritual, but there heart is away from the Lord.
Same as one who worship the Lord in the church every Sunday but do not obey God's word when He go out of church. It is detestable things to the Lord.
How?
Let me be a real follower of God, fully obey God's word and do the right things in my daily life. Reform my ways and my actions. Worship the Lord with all my mind, all my heard and all my strength.
