I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. (Gal. 2:20)
I never need to ask for an open heaven because the Veil of the Temple was torn when Christ died. I am The temple of the Living God, and heaven is already open for me, not because I asked, nor because I somehow deserved it, but because the Blood of Jesus has made it so.
Nor do I live by my own faith. God forbid, for my own faith would fail many times over before I could finish my journey. Indeed, I live by the faith of the Son of God, who loved me, and gave Himself for me. This is why I can do all things in Christ. He promised that HIS grace would be enough, and it is.
He loved YOU.
He gave Himself for YOU.
He put His Spirit in YOU.
Every prayer you could ever set before the Father has already been answered at Calvary.
