How do we know that God's will is effective in salvation?

The effectiveness of God's will in salvation is rooted in His absolute sovereignty. Isaiah 46:10 confirms that God declares the end from the beginning and that His counsel will stand, meaning His intentions in the matter of salvation cannot fail. Unlike human intentions, which can be thwarted, God's intentions are guaranteed by His omnipotent power. The Scripture emphasizes that He works all things according to His will, reinforcing the belief that the salvation of the elect is sure and true based on God's promises.
