How do we know Christ makes a difference in believers?

The distinction between those who belong to Christ and those who do not is fundamentally anchored in the presence of Christ within them. As stated in Galatians 3:26, 'For you are all children of God by faith in Christ Jesus.' The difference is not based on external appearances or actions but on the internal reality of Christ's redemptive work. Much like wheat and tares appear identical when they first grow, it is only through maturity and the evident fruit of faith that believers can be distinguished. This internal transformation is essential as it leads to a life transformed by the gospel, resulting in humility and dependence on Christ rather than self-righteousness.
