No, brother, it shouldn't. Maybe for you it should be. Maybe you have to contemplate that attribute of God in order to arrive at assurance of God's acceptance of you. But I do not.
I'm very assured of my salvation in Christ, and I have never to my knowledge had to think of God's sovereignty to come to that.God is sovereign, no doubt; and that is not in dispute, not to me.
And, as I have said, I haven't for a long time had any doubts about my acceptance in Christ nor my assurance of eternal life forever with Him. It comes from His Word and the fact that I have responded to Christ in faith exactly as His Word says.
He is sovereign, but my assurance is through His Word.
This gives no assurance unless one assumes they are elect. That is an assumption, not faith in Christ as Savior and payment for sin.
That would be fine if one knew they were elected; but that is a subjective mental assumption. One doesn't wake up one day and have this epiphany, "hey, I'm one of the elect!" and then come to saving faith. And God doesn't tap you on the shoulder and say "hey, you're one of My elect." It would be wonderful if He did, but instead He asks us to receive His Son in faith.
One knows he is elect because he believes in Christ. If you're elect, you believe. If you believe, you're elect.
As I said before, and it is becoming increasingly more obvious: this is quite possibly the cause for many people's lack of assurance; because people are telling them their assurance of salvation is to be based on something totally apart from them and having quite possibly nothing to do with them. Assurance comes only from a personal contact between the person and God. It is what God did for them personally through Christ, not because He happens to be sovereign and can choose who He wants and reject who He wants.
I merely ask that you give this consideration, brother, because I think this approach is doing many people harm.
Blessings,
