Many Christians fail to see the bondage to the law. They do not see that the legalism they espouse under the guise that not to be legal has to mean laziness and license. The fuel of self-righteousness makes this a intoxicating addiction to them.
These Christians do not understand the liberty in Christ. Paul said that the Judaizers wooing the disciples back to law keeping were trying to shut them out. That must mean to shut them out of the wonderful freedom in Christ to live Christ Paul was experiencing and laboring to bring them also into.
" They are zealous of you, but not rightly; but they desire to shut you out that you may be zealous of them." (Gal. 4:17)
From what was Paul saying they were trying to shut the Christians OUT of ?
It must be the realm of liberty and freedom to LIVE in union with Christ as the heavenly "power steering" empowering them to live the highest life. Paul and his co-workers were in the realm. Paul was bring the Galatian Christians also into that realm.
But the Judaizers wooing them back to legalism and law keeping to be justified to God were shutting them out of this realm.
Paul was laboring as an expectant mother to have the living Christ 'formed"
in them, liberating them from code keeping to blending "organically" with the indwelling Christ.
"My children, with whom I travali again in birth until Christ be formed in you." (v.19)
If he can only get the implanted Christ to be formed in them, to grow, take shape, take over, fill up completely, saturate, permeate so that they are living in an "organic" blending with Jesus Christ !
