Religions like Islam, Hinduism, Buddhism, Confucianism and others. Why?
Because:
"No one can come to Me unless the Father who sent Me draws him, and I will raise him up at the last day." (John 6:44)
"And we know that God works all things together for the good of those who love Him,
who are called according to His purpose. For those God
foreknew, He also
predestined to be conformed to the image of His Son, so that He would be the firstborn among many brothers. And those He
predestined He also
called, those He called He also
justified, those He justified He also
glorified." (Rom.8:29-30)
"
For He chose us in Him before the foundation of the world to be holy and blameless in His presence. In love
He predestined us for adoption as His sons through Jesus Christ, according to the good pleasure of His will, to the praise of His glorious grace, which He has freely given us in the Beloved One." (Eph.1:4-5)
"Not only that, but Rebekah’s children were conceived at the same time by our father Isaac. Yet, before the twins were born or had done anything good or bad—
in order that God’s purpose in election might stand: not by works but by him who calls—she was told, “The older will serve the younger.” Just as it is written: “Jacob I loved, but Esau I hated.” What then shall we say? Is God unjust? Not at all! For he says to Moses,
“I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.”
It does not, therefore, depend on human desire or effort, but on God’s mercy. For Scripture says to Pharaoh: “I raised you up for this very purpose, that I might display my power in you and that my name might be proclaimed in all the earth.”
Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden." (Rom.9:10-18)
"The inhabitants of the earth whose
names have not been written in the book of life from the creation of the world will be astonished when they see the beast, because it once was, now is not, and yet will come." (Rev.17:8)
Conclusion: Those who are involved in religions like Islam, Hinduism, Buddhism, etc., their names were not written in the book of life from before the world was created and therefore God is not calling them. He is not drawing them to his Son. Although, there are people who belong to God whom he calls out of those religious system. It does not, therefore, depend on human desire or effort, but on God’s mercy.
