Psalm 107:9 For He satisfies the longing soul, And fills the hungry soul with goodness.
When we are willing to listen to God and obey Him we find He is more than willing and faithful to supply our needs and fill us with joy and peace.
This is not to say we will all have an abundant earthly life if we just believe in God but rather our souls will be filled with all of our needs.
We will also find He does look after us and does supply our needs in earthly ways which would otherwise seem improbably or even impossible.
I personally enjoy seeing how much God does in my life as a live a life depending more on Him each day. It is not always easy, but very fulfilling!
