It is true that each person should bear their own burden, but we must bear in mind that it is good to support our brothers in difficult moments, because with this we are bearing their burden, giving them strength so that they can continue.
It is good to highlight the great performance that many have on the Lord’s path, but also when we notice these actions of forgetting the difficult moments that your brother is going through and you do not give him a hand, when you do not support him, but you judge him, this will be seen somewhat arrogant.
Unity in the Lord is this, that even if you do not carry your brother’s burden, then help him to continue forward in the Lord, that the strongest help the weakest, this is what the Bible commands us.
