I want you to know the length and breadth of your portion in Christ. I want you to understand the full amount of the treasure to which faith in Jesus entitles you. You have found out that you are a great sinner. Thank God for that. You have fled to Christ for pardon and peace with God. Thank God for that. You have committed yourself to Jesus for time and eternity – you have no hope but in Christ’s blood, Christ’s righteousness, Christ’s mediation, Christ’s daily all-persevering intercession. Thank God for that. Your heart’s desire and prayer is to be holy in all manner of conversation. Thank God for that. But oh, lay hold upon the glorious truth – that believing on Jesus you shall never perish, you shall never be cast away, you shall never fall away! It is written for you as well as for the apostles, “My sheep shall never perish.”
