17 Yea, in the strength of the Lord did we go forth to battle against the Lamanites; for I and my people did cry mightily to the Lord that he would deliver us out of the hands of our enemies, for we were awakened to a remembrance of the deliverance of our fathers.
In verse 17, Zeniff comments that he and his men went forth in the strength of the Lord. And because they did this, they were victorious in the battle they were about to fight.
Now hopefully we are not going into a literal battle the way Zeniff was, but we all fight battles every day. Battles against temptation and sin. Battles against our circumstances. Battles against anger or despair or hopelessness. These battles are of great importance to us because they affect our lives.
If we can remember to go forth in the strength of the Lord every day, in every battle, we will be able to come out victorious in our daily battles. Cry mightily to the Lord for deliverance... in other words, pray for help in your personal battles. The Lord will hear your cries and come to your aid.
