"Various trials" is defined as an array of different
types of struggles.
Heartache, sickness, marital strife, physical pain,
persecutions, feelings of neglect, misunderstandings,
being at odds with our children - all these and more
can be the trials we have in our lives, through
which God produces in us patience, which works
towards perfection.
James, as Kevin Pulliam explains, does not belittle
the seriousness of these struggles, but issues the call
for believers to live for God's glory.
