"God gave them up ..." - Romans 1:24, 26, 28
There are control gates that regulate the flow of water to Niagara Falls.These gates are about a mile upstream from the falls and are often called "the point of no return," because any boat or person caught in the current beyond them will be carried right over the falls. On rare occasions lives have been lost by going beyond the gates. No one can be blamed, because a choice was made to ignore the warning.
The Scriptures are chock full of warnings. The holiness of God is clearly taught, the wrath of God toward evil is honestly stated and the grace of God is beautifully presented. Our journey into the future is full of moments when warning signs need to be considered. When someone chooses to venture past the gates, and live beyond "the point of no return" they will experience Divine wrath and condemnation. God must not be blamed, because the choice was made to ignore His warning.
What is "the point of no return", you may ask? The answer is difficult for us to pinpoint, but John writes in 1 John 5:16, "There is sin that leads to death; I do not say that one should pray for that." Between Romans 1 and 1 John 5 we have sober warnings. Seek and embrace the grace of God to avoid the gates that lead to "the point of no return".
Think about this: "Sin drives men mad. Against their reason, against their best interests, they follow after that which they know will destroy them."
- C. H. Spurgeon
