that you keep the commandment without spot, blameless, until the appearing of our Lord Jesus Christ;
until the appearing of our Lord Jesus Christ: The keeping of this commandment was to be unending or until His appearance or manifestation (Titus 2:13; 2 Thessalonians 2:8). Paul’s statement should not be taken to infer he anticipated the Lord’s return would be in Timothy’s lifetime. He is saying to Timothy to keep the commandment during his lifetime, for in this fashion it will be preserved until the Lord cometh.
