How do we know God's chosen us for salvation?

We know that God has chosen us for salvation through the testimony of Scripture and the inward change we experience when we come to faith in Christ. John 15:16 tells us that we did not choose God, but He chose us. This choice is not based on anything we have done, but solely on His grace. Romans 8:28-30 elaborates on this concept, illustrating that those whom God foreknew, He predestined to be conformed to the image of His Son. This provides us assurance and a foundation for spiritual happiness, knowing our salvation rests securely in God's sovereign will.
