“You wrongdoers try to frustrate the plans of the lowly one,
But Jehovah is his refuge.”
~Psalm 14:6

Should we find that we will not be able to reach the goals we have set for ourselves in God’s service, we should not become discouraged.
Circumstances change and no one has full control over their own situation.
Not only are we susceptible to our own sinful inclinations, but we may find ourselves to be victims of the wrongdoings of others (Rom. 3:23).
While these factors may have a negative impact in our service to God, they do not impede our being loyal to Him.
Therefore we should continue serving God zealously alongside His congregation to our fullest capacity, because He will continue being our Protector, giving us all we need to be happy (Ps. 37:28; Ps. 145:16; Heb. 6:10-12).
