"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. Truly I tell you, they already have their full reward. But when you pray, go into your inner room, shut your door, and pray to your Father, who is unseen. And your Father, who sees what is done in secret, will reward you. And when you pray, do not babble on like pagans, for they think that by their many words they will be heard. Do not be like them, for your Father knows what you need before you ask Him. So then, this is how you should pray:
‘Our Father in heaven, hallowed be Your name. Your kingdom come, Your will be done, on earth as it is in heaven. Give us this day our daily bread. And forgive us our debts, as we also have forgiven our debtors. And lead us not into temptation, but deliver us from the evil one." Matthew 6:5-13
"Be anxious for nothing, but in everything, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus." Philippians 4:6, 7
"The LORD is far from the wicked, but He hears the prayer of the righteous." Proverbs 15:29
