Believers can strengthen the hands of the wicked by approving of their works or remaining silent concerning their God’s view of those wicked works.
Sin causes a man's strength to fail. On the contrary, "the way of the LORD is strength to the upright." Man's choice to sin will eradicate his strength.
The right kind of sorrow is often needful and brings with it certain benefits. Yet, it is in the joy of the LORD that God's people specifically find strength.
Man is not promised an endless supply of strength for him to store up. Rather, God promises to provide the necessary grace and strength for the present trials.
