Pray to the Lord as if you were talking to your father. There is no tricks to it, the Lord knows ahead of time what we are going to ask of him, but he likes to hear us ask. This is having communication with the Lord as one that we love and trust with all our Heart. The bible tells us in:
Matthew 6:1
"Be careful not to do your 'acts of righteousness' before men, to be seen by them. If you do, you will have no reward from your Father in heaven.
Matthew 6:5
"And when you pray, do not be like the hypocrites, for they love to pray standing in the synagogues and on the street corners to be seen by men. I tell you the truth, they have received their reward in full.
Matthew 6:6
But when you pray, go into your room, close the door and pray to your Father, who is unseen. Then your Father, who sees what is done in secret, will reward you.
Matthew 6:8
Do not be like them, for your Father knows what you need before you ask him.
When the disciples asked Jesus how they should pray Jesus taught them how to pray in this order:
Our Father, who art in heaven, Hallowed be thy Name. Thy Kingdom come. Thy will be done in earth, As it is in heaven. Give us this day our daily bread. And forgive us our trespasses, As we forgive them that trespass against us. And lead us not into temptation, But deliver us from evil. For thine is the kingdom, The power, and the glory, For ever and ever. Amen
I always come to the Lord in Jesus Christ name his precious son, then I start to pray the Lord's Prayer first, then I ask for forgiveness of my sins, and thank him for all the blessings he has already given me. Then I pray for my petition, and end with thanking him in advance. I hope this will also help you to understand more about prayer.
May the Lord guide your steps always and make you a great servant of his as you lean more of him.
