I do not know the S.I unit for measuring faith, but I do know that faith as small as mustard seeds can move mountains as big as Everest.
Now, I don’t know why you would want to move Mount Everest from its current location. Maybe to boost tourism in the new location, (Nigeria can really use the money, if it won’t get stolen first), or just to prove a point. But I do know that man’s want are insatiable.
As for needs, that’s where faith needs to be practiced. Wants and needs, as in a secondary school student wanting a car to show off to his friends while a man with a family of 5 needing a car to help move them around. A man wanting the rain to stop falling so he can go “turn up” in the club with his friends and a woman needing the rain to fall all night to boost her farm produce.
When you can separate your wants and needs, then you can pray appropriately.
Thank God for the era of grace. Lots of “modern Christians” are so in love with the concept of “grace“, cos they are in a hurry to abuse it. The grace I am grateful for is the one that begins with the rending apart of the veil in the temple upon the death of Jesus Christ at the cross.
It opened a chapter in human relationship with God, whereby anyone can talk to Him through faith, without needing an intermediary or priest. We can ask God for any need, beginning at salvation, but not ending at financial resources, good health, wisdom, or direction in life.
Faith like a grain of mustard seed will move mountains, now imagine the strength of a faith as massive as a mountain. That brings us to growing in faith. The level of your trust in God five years after you first believed in him shouldn’t be the same as when you just started your relationship with Him.
 “But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law.” Faith here is different from the rest because it is the one fruit that is directed more towards oneself rather than others
That brings us to selfishness. “Ask and you will receive“, “I will give you the nations for a possession“. That doesn’t necessitate praying for all your enemies to drop dead, nor all your rivals failing woefully.
“The earth is the Lord’s and its fullness thereof“. You can have all your needs met without someone else giving his life for it.
Is your faith as like a mustard seed or is it growing? Do you trust absolutely in God or do you need an assistant god? Can God trust you with responsibilities that comes with Faith in Him?
Remember “faith is the substance of things hoped for, the evidence of things not seen.”
