2 Timothy 4:1

2 Timothy 4:1 I solemnly charge you before God and Christ Jesus, who is to judge the living and the dead, and by His appearing and His kingdom. 

Not many believers realize that when the Lord Jesus comes back, He will not come as the merciful God or as the gracious Savior but as the righteous Judge. Christians should be warned and encouraged to prepare themselves to stand before this Judge. 

the bible has clearly told us that when the Lord comes back, at the judgement seat of Christ, we, as His believers, all need to give an account to Him. at this time, He will not be the merciful One to us, where we can beg His mercy and He will just let us go. No. He will be the righteous Judge, the foundation of whose throne is righteousness and justice. He will judge us according to righteousness how we conducted ourselves in our daily living. if we have this view, His coming will be a warning and reminder to us, that we can not live our life on the earth in a loose way. rather, our daily living should be governed in the light of His second coming.
