Its not about believing that God is real, Satan believes God is real
Its about being close to Him and doing whatever He wants you to do, you need to have a relationship with Him and you need to love Him
And you need to honor Him
He wants us to be happy and He will supply all our needs
Philippians 4:19 (KJV):
But my God shall supply all your need according to his riches in glory by Christ Jesus.
Matthew 6:8-15 (KJV):
... 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 out 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:
But if ye forgive not men their trespasses, neither will your Father forgive your trespasses
