What Has Thou To Do?

Psa 50:16 — Psa 50:17 (KJV)

But unto the wicked God saith,
What hast thou to do to declare my statutes,
or that thou shouldest take my covenant in thy mouth?
Seeing thou hatest instruction,
and castest my words behind thee.

I can't help but think of generations down, that John the baptizer would say of the Pharisees and Sadducees - "O generation of vipers, who hath warned you to flee from the wrath to come?" (Matt 3:7)
These were a group which were supposedly experts, teachers in the Old Law, and yet was sharply criticised by John and later even Jesus Himself (esp. Matt 23).
Indeed, when we choose to ignore any part of God's commands, we have no business in declaring His Word.
God forbid, yet this is the reality of the selfish desires of men, even till today, even as we observed the denominational confusion.
Are there morally good people among these "wicked"? Oh absolutely! Just as there are morally good, even superior, souls among those who practice other forms of religion or even the atheist!
What then? Shall we hold our peace and just let them do as they will?
God forbid! To do so is perhaps the most heinous  thing to do to another! If we truly loved souls the way Jesus did, we would spare no effort to at least bring the gospel to such. It is not for us to judge but for us to preach the truth.
It is not the "end game" while one still has a breath of life. As John the baptizer will subsequently say -
"Bring forth therefore fruits meet for repentance:" (Matt 3:8). He knew his place. He was merely relaying the message. Yet all the same, if men, regardless of so-called believers in the denominational world or outright deniers of God, will not turn from their old ways, the label of "wicked" remains.
What is our repsonse? To continue to seek after God's Word in its pure simplicity; speak the truth IN LOVE (Eph 4:15), withholding nothing, excepting no one; and continue in good works that God may be glorified in us.
