Do you ever have one of those days or times when you're just frustrated in general for no particular reason? This verse jumped out at me this morning:
Romans 8:20 "For the creation was subjected to frustration, not by its own choice, but by the will of the one who subjected it, in hope"
What I glean from that verse (and the ones following it) are as follows:
1) Frustration is actually something the God wants for us to feel at times
2) This frustration is felt by all creation so you're not alone in feeling that way and at times there may actually not be a concrete or definable reason for your frustration
3) As a Christian we do have hope since we can look forward to our new bodies
4) However as a Christian, we also still "grown inwardly" as we wait since we don't yet experience all that is to come in heaven.
Hopefully I haven't taken too much out of context. Those are simply my thoughts on these verse at this point in time.
