It is imperative that men speak the truth, for “he that speaketh the truth sheweth forth righteousness,” and his lip “shall be established for ever.”
Strength is not tested or demonstrated during times of ease. Rather, it is during times of adversity that one finds out just how strong he is.
The Lord is the strength of His people. While it is true that we are called to do our part, God must add the necessary strength to accomplish the work.
