God will not withhold anything that is good FOR you, FROM you if you walk upright in His sight! (Psalm 84:11)
God knows THE PLAN He has for you. His good plan will give you hope and a future!
(Jeremiah 29:11) His plan is always best!
The plan you make without consulting God, may, or may not, be THE PLAN He has for you!
If you make your plan, and THEN ask Him to bless it, He is under no obligation to do so!
Actually proceeding. with your plan without consulting God FIRST may delay God's plan,
or even stop His plan from manifesting in your life!
