Full effect being complete and inferior to none. (James)

But let patience have her perfect work, that ye may be perfect and entire, wanting nothing. James 1:4

Let:  comprise, involve, possessed with

Patience: steadfastness, constancy, endurance (the characteristic of a man who is unswerved from his deliberate purpose and his loyalty to faith and piety by even the greatest trials and sufferings)

Perfect: brought to its end, finished; lacking nothing necessary to completeness

Work: an act, deed, thing done: the idea of working is emphasized in opposed to that which is less than work

Entire: complete in all its parts, in no part lacking or unsound

Wanting: to lag, be inferior

Nothing: none, not

Be possessed with steadfastness, constancy, and endurance so that I'll know the full effect being complete and inferior to none. 

My brethren, count it all joy when ye fall into divers temptations; knowing this, that the trying of your faith worketh patience. But let patience have her perfect work, that ye may be perfect and entire, wanting nothing. James 1:2-4

There is a progression in these verses, with a purpose! But it's not a "once and I'm done", idea. It's a constant and ongoing process. It ALL begins with choosing the MAXIMUM Calm Delight!
