When did he make that decision? Was it before you were born, before the foundation of the earth, or did he have to sit back and wait for you to either get baptized or to make some decision in adulthood?
The bible says that those who whave been chosen have been chosen before the foundation of the earth. Do you believe that? If so, then how is God's choice to save you any different from God's choice to save Mary?
The question is, "Have I chosen Him?"
Really? If God chose you can you veto his choice? Or is his choice the final say?
There are many ways to deny Jesus, and I am trying not to do them.
Is your salvation dependent upon the things you do or is it wholly dependent upon God's mercy?
Of course I can veto God - just as Adam and Eve did in the Garden. My salvation is dependent on my acceptance of God's mercy. God extends His mercy to all, but many reject it. Many people hate God and then there are others with varying degrees of non-interest. I am trying, with all I say and do, to show Jesus how much I love Him. Being still afflicted with a free will, I fail, because I sometimes choose myself over others. Jesus gives us many examples of those who do not do His will and He will judge us all. But as He said of the woman who wiped His feet with her hair, "She is forgiven much, because she loved much." So love is the key. We love because He first loved us. How do we love? By showing His love to others and by doing His will, in everything we say and do.
