Chapter I: THE INTERNAL CALL.--The elements of this are: 1. A fixed and

earnest desire for the work._ "This is a true saying, if a man desire the office of a bishop, he desireth a good work" (1 Tim. iii. 1). There must be desire; for no man will succeed unless the work enlists the whole enthusiasm of his being. This is more than a love of declamation, a glow in the work of composition, or a taste for the studious, literary life of a pastor: it is a quenchless enthusiasm for the work as the proclamation of God's message and the means of saving men. It springs from love to Christ and love to the work itself. Paul said: "None of these things move me, neither count I my life dear unto myself, so that I might finish my course with joy, and the ministry which I have received of the Lord Jesus, to testify the Gospel of the grace of God" (Acts xx. 24). 2. _An abiding impression of duty to preach the Gospel._ The apostle Paul said: "Necessity is laid upon me; yea, woe is unto me, if I preach not the Gospel" (1 Cor. ix. 16). Not always, indeed, will this inward impulsion to the work be so distinct and imperative, but it will always be felt, and with greatest force as the soul draws nearest to God and the true nature of the ministry is most clearly perceived. Hence, in determining the question of vocation much prayer is necessary, and the convictions which predominate in the soul, when most consciously in God's presence, are to be most carefully considered. 3. _A sense of personal weakness and unworthiness and a heartfelt reliance on Divine power._ This, indeed, is not an infallible test, for youth is naturally self-confident, and in the case of some most useful ministers a reliance alone on the Divine Arm has come only after long and bitter experience of self-failure. But a self-confident spirit should certainly suggest the fear of self-deception, since it can only spring from a false self-estimate and from wholly inadequate views of the work. Paul said: "Such trust have we through Christ to God-ward; not that we are sufficient of ourselves, but our sufficiency is of God, who also hath made us able ministers of the New Testament" (2 Cor. iii. 4-6).
