Has Christ become of "none effect"?

Has Christ become of "none effect"? He became of "none effect" to those Galatian believers who had begun in the Spirit but had left the first love of "simplicity of devotion to Christ." But has Jesus become of "none effect" to us? 

Are we experiencing the FULL EFFECT of His joy making our joy full? Is the effect of the abundant life He came to bring unmistakably evident in our spiritual life now? Have we lost a vibrant connection with our Lord? Is our joy FULL like His, unspeakable and full of glory? Are we experiencing His peace flowing like a river welling up within us? 

We know in our head that all of God's fullness dwelt bodily in Christ, but are we experiencing the effect of being made complete in every area as God intended from Christ dwelling in us? Are we effectually being enabled to do "all things through Christ who is strengthening us"? 

OR 

Is there a disconnect between the faith we profess and the "effect" we experience? Is all the dynamic grace of Christ powerfully working in us or have we succomed to a state where His abundant grace is no longer "effectually at work"? 

The question is worth answering honestly - has Christ become of "none effect" or is His grace powerfully at work in me today? He has not changed, but have I lost connection with Him? Is it I "can" do all things thru Christ or I "could" at one time?
