Why is it important for Christians to be on the Lord's side?

The importance of being on the Lord's side lies in the distinction it makes regarding the nature of God's will versus man's. In the sermon, it is emphasized that there is no neutral ground; one is either for the Lord or against Him. This choice directly relates to one's understanding of salvation—either affirming God's sovereign grace or upholding a view of salvation that grants merit to human actions. Being on the Lord's side means rejoicing in God's glory and the certainty of His chosen elect, aligning oneself with the fullness of His grace and refusing to attribute any part of salvation to human efforts. This allegiance is fundamental to the Christian faith, as it drives believers to trust fully in Christ alone for salvation.
