> I keep praying for the best to come his way.
what do you mean by 'the best' ?
do you mean that you want his circumstances to change, that he gains wealth and health and no longer feels grieved in his heart from the wounds done to him ?
or do you have the understanding that the very best that can fulfil the soul is having peace with God, one's maker and creator who ordained all these evils should come to pass so as to bring about glory to Christ – this same Christ who in rescuing and enlivening the deadest of soul, shows extravagant mercy and infinite compassion for none of us deserve any good thing by His hand
do you also understand that having fellowship with one's Creator, where one follows the discipline of the Christ and walks the path of He who was 'a man of sorrows and acquainted with grief', one isn't necessarily freed from sadness but is rather trained to bear such sorrow in this life, carrying a cross just like their Master
have you experienced grief yourself, OP; and are you aware that just as one can feel lifelong sorrow over the death of a loved one, one can have lifelong grief over the death of hopes and dreams that childhood abuse can kill ?
if you don't have that understanding, your attempts at healing your friend may be as useful as applying sticking-plasters to someone who needs open-heart surgery, and while your first-aid might be useful in the short-term, such as what a field medic might perform on a battlefield; unless your friend is brought into the presence of the Great Physician, he will never experience true healing and wholeness – for no-one is able to mend the broken-hearted like the one who made that heart in the first place
