Attempting to execute every burden you are called to carry.
Many intercessors forget that they were called first to intercede and then move immediately into an attempt to execute. The grace to intercede is different from the grace to execute. An intercessor may clearly see a problem, feel its weight, and receive insight about it without being the person appointed to organize, confront, lead, fund, or physically carry out the solution.
This does not mean that God will never call an intercessor to act. At times He will. The mistake is assuming that every burden is also a personal commission to execute. The intercessor must remain before God long enough to discern whether the instruction is to pray, to speak, to act, or to release the matter to someone with a different grace. Moses held up his hands while Joshua fought the battle; both assignments mattered, but they were not the same assignment.
“Now there are diversities of gifts, but the same Spirit… and there are diversities of operations, but it is the same God which worketh all in all.”
