Not being separated from the love of God; and sin separates us from God are totally contrary to one another. These two statements are antonymous not synonymous.
Wake up professed people of God. We are to be a witness of God’s power to deliver us from sin; His living walking witnesses of His love, the fruit of the Spirit in all our living, conversations, and thoughts contemplated.
God will give self-willed people over to their own reprobate mind… Don’t be in this category of people.
It is written:
Romans 1:28-32 KJV
 “And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;  Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,  Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,  Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:  Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.”
God did not spare a third of the angels! He did not spare Lucifer who was a Light-bearer; but is now Satan, the devil. God loves all His creatures. Nevertheless, God hates sin. Sin separates us from God. In the holy scripture above, are sins of sinners—sinners who hold on to sin and reject the Redeemer, refuse redemption. God will not override your choice and force you to receive His love, His righteousness, His sanctification, the fruit of the Spirit. God will not take that which you really want to hold on to. Period.
Nothing, nor no one can separate us from the love of God. But, our choice to sin, sin separates us from God.
God’s love is eternal. Dead or alive, in sin or restored. God loves all. His love gives us freedom of choice and He will allow our choice even if it will bring to us the consequence of the second death.
