67问：何谓有效的恩召？
答：有效的恩召乃上帝大能与恩典的作为（约5:25；弗1:18-20；提后1:8-9），就是：1）祂的行动完全是出于自己对选民白白的奇恩妙爱，并非因为选民自己有什么吸引祂的地方（多3:4-5；弗2:4-5，7-9；罗9:11）；2）祂在悦纳的日子，借着自己的圣言和圣灵，将他们邀到、引到耶稣基督面前（林后5:20，比较林后6:1-2；约6:44；帖后2:13-14）；3）祂以救赎之光启迪他们的心思（徒26:18；林前2:10，12），更新并有力地扭转他们的意志（结11:19；36:26-27；约6:45），使他们已死在罪恶过犯中的人能够甘心乐意、自由自在回应祂的呼召，领受所赐、所传予他们的恩典（弗2:5；腓2:13；申30:6）。
Question 67: What is effectual calling?
Answer: Effectual calling is the work of God’s almighty power and grace, whereby (out of his free and special love to his elect, and from nothing in them moving him thereunto) he does, in his accepted time, invite and draw them to Jesus Christ, by his Word and Spirit; savingly enlightening their minds, renewing and powerfully determining their wills, so as they (although in themselves dead in sin) are hereby made willing and able freely to Answer: his call, and to accept and embrace the grace offered and conveyed therein.
68问：是否只有选民能有效蒙召？
答：唯独所有的选民能蒙受有效的恩召（徒13:48）；其他人虽或也经常触及上帝圣言外在的呼召（太22:14），以及圣灵某方面一般性的作为（太7:22；13:20-21；来6:4-6），但由于他们对所显于他们之恩典蓄意忽略、心存藐视，弃自己于不信之中，故无法真正归向耶稣基督（约12:38-40；徒28:25-27；约6:64-65；诗81:11-12）。
Question 68: Are the elect only effectually called?
Answer: All the elect, and they only, are effectually called; although others may be, and often are, outwardly called by the ministry of the Word, and have some common operations of the Spirit; who, for their wilful neglect and contempt of the grace offered to them, being justly left in their unbelief, do never truly come to Jesus Christ.
