Animals are such agreeable friends - they ask no questions, they pass no criticisms.
For every man shall bear his own burden. The first means a burden that is too heavy for any one person to be able to carry alone. In other words, when a fellow Christian is under a burden that is impossible for him or her to bear alone, we are to help . On the other hand, if we carry someone's knapsack for them when they are quite capable of carrying it themselves, we aren't helping them if we carry it for them, but keeping them over dependent and allowing them to use us. In this case neither one of us is being helped.
