“Do you believe that God planned for the founding fathers of this country to advocate breaking up black families in slave trade and bless america?”
I believe, as Paul did, that Romans 8:28-39,
“And we know that all things work together for good to them that love God, to them who are the called according to his purpose. For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren. Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.
What shall we then say to these things? If God be for us, who can be against us? He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things? Who shall lay any thing to the charge of God’s elect? It is God that justifieth. Who is he that condemneth? It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.
Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter. Nay, in all these things we are more than conquerors through him that loved us. For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.”
That includes freedom, good health, financial security, success, good looks, fame, intact family, peace; none of those things can separate us from the love of God. He tailors the right conditions for our salvation, even to the death of his son. He uses the gifts of illness, addictions, financial ruin, injury, ignomy to bring us to him. So to answer your question, God uses even slavery to bring his children to him, for circumstances do not determine our royal lineage, only faith in him. What does it profit a man if he has all of the freedom in the world and loses his soul?
Does he bless America is a question only he knows the answer. A look at the spiritual condition of America would lead one to say the blessing is turning into a curse.
Phil. 4:11, “Not that I speak in respect of want: for I have learned, in whatsoever state I am, therewith to be content.”
1 Cor. 7:21-22, “Art thou called being a servant? care not for it: but if thou mayest be made free, use it rather. For he that is called in the Lord, being a servant, is the Lord’s freeman: likewise also he that is called, being free, is Christ’s servant.”
Eph. 6:5, “Servants, be obedient to them that are your masters according to the flesh, with fear and trembling, in singleness of your heart, as unto Christ;”
