Simple and trusting prayer

Matthew 6:5-15
Do not pray standing in the synagogues and on the street corners to be seen by men. Do not keeping on babbling like pagans, for they think they will be heard because of their many words. Do not be like them, for your Father knows what you need before you ask him.
Forgive men, your heavenly Father will also forgive you.
Lord's Prayer:
Our Father in heaven, hallowed be your name,
10 your kingdom come,
your will be done, on earth as it is in heaven.
11 Give us today our daily bread.
12 And forgive us our debts, as we also have forgiven our debtors.
13 And lead us not into temptation, but deliver us from the evil one.
Jesus also tells his followers to give and pray and fast without drawing attention to themselves. God will reward them.
Prayer is to be simple, trusting: as children come to a loving Father, eager to please, conscious of failings. It is expressed in the model prayer Jesus gives his disciples.
Why?
Do not be pagan or hypocrites, they do not know the meaning of pray.
God knows what we need so my prayer should always use the same words but with more love and caring to Kingdom of God.
How?
Change my prayer today with love to my heavenly Father.
