We are indeed prone to wander. God is the God of mercy and justice, while we are not true to Him or merciful or just to each other. 1 Cor 4 exhorts us “not to think beyond what is written, that none of you may be puffed up on behalf of one against the other. For who makes you differ from another? And what do you have that you did not receive? Now if you did indeed receive it, why do you boast as if you had not received it?"
