Ah, Brother, a sadness indeed, one I deal with daily, for I too have many family members who have no notion of Yeshua.
And suicide...well, a familiar one to me, in the desiring of doing so, for many years in my youth. I thought long and hard, and longingly and angrily day by day.
And with suicide, or attempted suicide we are looking at anger...anger at the world that has hurt us , turned our anger, often just and righteous anger against ourselves out of the belief that we must be the cause of all the wrongness in our lives, rather than understanding the sin nature that is in us.
Yeshua said "Be angry, and sin not." Ephesians 4:25
Suicide and the outworking of anger against the temple of the body is indeed a sin, but my brother, we all sin, every day, and we are forgiven.
There is nothing so grave that one cannot go to Yeshua with, and pray for forgiveness on, whether it is your sin, or another's.
Despite the opinions of many, the attempted death of oneself is not an action of despair, which some consider to be an unforgivable grievance against the Ruach haKodesh, but an outworking of anger and confusion.
YHVH knoweth all things before we do them...do you not think that He will know how to deal with the afflicted?
He, who has loved us so much, will He not take all into consideration?
Remember also, that Yeshua has said that we shall have what we ask for, if we ask in faith.
Matthew 18:18-20
18. Verily I say unto you, Whatsoever ye shall bind on earth shall be bound in heaven: and whatsoever ye shall loose on earth shall be loosed in heaven.
19. Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven.
20. For where two or three are gathered together in my name, there am I in the midst of them.
As for those that do not believe...yet...it is hard indeed for us to see them in pain, and anguish and disarray, but again:
Matthew 18:19 Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven.
We pray, and we wait, but the end result for us all, although known to YHVH in advance, is yet a choice of each of us. YHVH gives us that freedom, to refuse Him, and we must give the freedom to those around us to reject our Beloved as well.
Even so, remember that prayer availeth much.
James 5:15
19. Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven.
Pray, my brother, and then rest in Yeshua.
