Many of us have experienced this with our parents:
"PLEASEEEEE, MOMMY AND DADDY! PLEASEEEE!"
Sure, God is our heavenly Father, but that doesn't mean we should treat Him like we did our parents when we were younger. It's important to remember why we became Christians in the first place, to stay out of a devil's hell and follow God's will and not our's.
How is asking God for permission the same as asking for His will? If you really want to follow God's will ask for His guidance instead.
"Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done."
- Luke 22:42, KJV.
When Jesus was speaking in this passage, He was praying before going to the cross. I doubt that Jesus wanted to be betrayed, beaten, scolded, yelled at, etc. and then die for sins He didn't even commit! His human flesh had the will to skip it all-together, but He understood what His Father's will was.
It is OK to ask for a request like Jesus did. God wants us to tell Him our true feelings, but the line is drawn when we come up with our own plan then ask for EXACTLY what we want. This thought process is way to self-centered, and that is unacceptable in God's eyes.
I know I've done it. I've crossed the line, and I'm sure many others have as well. Let us come to God and thank Him while presenting our requests to God and asking Him to guide us rather than guiding Him.
"9 After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name.
10 Thy kingdom come, Thy will be done in earth, as it is in heaven.
11 Give us this day our daily bread.
12 And forgive us our debts, as we forgive our debtors.
13 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."
- Matthew 6:9-13 (KJV)
