close the door,
and pray to your Father in secret (Mt 6).
Prayer usually is not easy for us. Therefore, Jesus gives us some advice how to do it. First of all: one praying needs to go to his/her 'inner room'. This inner room is a special place somewhere inside us. There one can meet God. This place should be closed for noises coming from outside. So one ought to close his/her ears not to listen to anything else but Him. Moreover, God is not an abstract Being but Father waiting to love His children. From that reason, one do not need to worry nor be scared but just trust completely.
