Carry each other’s burdens, and in this way you will fulfil the law of Christ. 

…for each one should carry their own load.

Galatians 6:2, 5

‘The burden’, as in ‘Bear one another’s burdens’ (v. 2), baros in Greek, has a focus on the fact that it is too hard or heavy, while ‘the load’, as in ‘Each will have to bear his own load’ (v. 5), fortion, has a focus on the fact that it is a consequence of something else.

When you think of lightening a brother’s burden, the fact that it is his burden does not make it any lighter for you to carry, because the minute you take it on, it is yours to bear, not someone else’s that you are carrying as a favour. It is real.

Then, who would dare carry someone else’s burden when you have enough of your own? – Under the old law, nobody. They were busy loading others while they themselves carried nothing (cf. Matt. 23:4; Luke 11:46). But under the new law, the law of the Spirit and of Christ, the others’ burden (v. 2) and my own load (v. 5) cannot really be separate. The ones who are born of the Spirit at last are fit to restore a brother who is still under the old law. This way, they prove to themselves that they are now truly under the new law of the Spirit and Christ, who has transformed the untransformable.

So by the Spirit, they have the strength to struggle with casting off false imposition, false pretention, false pride and guilt, etc. that belong to the old law and with taking on the weight of carrying others’ burdens that belongs to the new. The Holy Spirit, who powerfully gave birth to them, still comes by and strengthens them with his own power of raising the dead. 

These Spirit-born people are like the wind blowing freely (cf. John 3:8). They do not know from where they suddenly have this will to ‘love’ the enemy so much as to carry their burdens. Nor have they a precise goal to achieve out of it. They may fail, but they are not afraid any more because they know that the Spirit does not leave them. It is the load (v. 5) of the grace of Christ, who carried our burden (v. 2) to transform even our origin.

Lord, let us not fill ourselves with slightly different but still our own desires and ideas. When you have transformed us, that transformation is complete and perfect. Let us not try to escape from it, like a dog returning to its vomit. Let us be completely and perfectly yours in the things we think, say, and do to ourselves and others. Give us our daily strength, O Lord Holy Spirit.
