Nehemiah was constantly in prayer; every new trial he faced with prayer to God. Here he is asking God for the preservation of his reforms.
Every Christian should have that: great love for the Lord, great rejoicing in experiences of God and answered prayer and advance, but also holy godly fear. I cannot offend him. I do believe the Lord disciplines his children. I do believe that great wrongs will be corrected. I fear that, and I will be careful. I will not be tempted to push beyond these boundaries, and do these wrong things. Something happens with an Eliashib, and today there are some awful compromises that you hear about. You think, ‘Whatever it is that Christian man thinking of? Has his faith failed? He no longer has a sense of fear; he thinks he can get away with doing outrageous things and awful compromises?’ We have to be careful that none of this allow faith to fail, or fear to fail, because holy fear and faith go hand in hand. Holy fear is such a reverence for God and such an awareness of his presence and being, that we dare not offend him.
