Jesus said,"And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. If ye shall ask any thing in my name, I will do it."
John 14:13-14

Jesus teaches this:

But when ye pray, use not vain repetitions, as the heathen do:
for they think that they shall be heard for their much speaking.
Be not ye therefore like unto them:
for your Father knoweth what things ye have need of, before ye ask him.
After this manner therefore pray ye:
Our Father which 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 debts, as we forgive our debtors.
And lead us not into temptation, but deliver us from evil:
For thine is the kingdom, and the power, and the glory, for ever. Amen.

For if ye forgive men their trespasses, your heavenly Father will also forgive you:
Matthew 6:7-15
