So, dear friends, whilst here we have a promise which specially applies, no doubt, to these twelve Apostles, and the result of which in them was different from its result in us, inasmuch as the Spirit's teaching, recorded in the New Testament, becomes for us the authoritative rule of faith and practice, the promise still applies to each of us in a secondary and modified sense. For there is nothing in these great valedictory words of our Lord's which has not a universal bearing, and is not the revelation of a permanent truth in regard to the Christian Church. And, therefore, here we have the promise of a universal gift to all Christian men and women, of an actual divine Spirit to dwell with each of us, to speak in our hearts.
And what will He speak there? He will teach us a deeper knowledge of Jesus Christ. He will help us to understand better what He is. He will show us more and more of the whole sweep of His work, of the whole infinite truth for morals and religion, for politics and society, for time and for eternity, about men and about God, which is wrapped up in that great saying which we first of all, perhaps under the pressure of our own sense of sin, grasp as our deliverance from sin: 'God so loved the world that He gave His only begotten Son, that whosoever believeth in Him should not perish, but have everlasting life.' That is the sum of truth which the Spirit of God interprets to every faithful heart. And as the days roll on, and new problems rise, and new difficulties present themselves, and new circumstances emerge in our personal life, we find the truth, which we at first dimly grasped as life and salvation, opening out into wisdom and depth and meaning that we never dreamed of in the early hours. A Spirit that bears witness of Christ and will make us understand Him better every day we live, if we choose, is the promise that is given here, for all Christian men and women.
Then note that this inward witness of Christ's depth and preciousness is our true weapon and stay against a hostile world. A little candle in a room will make the lightning outside almost invisible; and if I have burning in my heart the inward experience and conviction of what Jesus Christ is and what He has done and will do for me--Oh! then, all the storm without may rage, and it will not trouble me.
If you take an empty vessel and bring pressure to bear upon it, in go the sides. Fill it, and they will resist the pressure. So with growing knowledge of Christ, and growing personal experience of His sweetness in our souls, we shall be able, untouched and undinted, to throw off the pressure which would otherwise have crushed us.
Therefore, dear friends, here is the true secret of tranquillity, in an age of questioning and doubt. Let me have that divine Voice speaking in my heart, as I may have, and no matter what questions may be doubtful, this is sure--'We know in whom we have believed'; and we can say, 'Settle all your controversies any way you like: one thing I know, and that divine Voice is ever saying it to me in my deepest consciousness--the Son of God is come and hath given us an understanding that we may know Him that is true; and we are in Him that is true.' Labour for more of this inward, personal conviction of the preciousness of Jesus Christ to strengthen you against a hostile world.
And remember that there are conditions under which this Voice speaks in our souls. One is that we attend to the instrument which the Spirit of God uses, and that is 'the truth.' If Christians will not read their Bibles, they need not expect to have the words of these Bibles interpreted and made real to them by any inward experience. If you want to have a faith which is vindicated and warranted by your daily experience, there is only one way to get it, and that is, to use the truth which the Spirit uses, and to bring yourself into contact, continual and reverent and intelligent, with the great body of divine truth that is conveyed in these authoritative words of the Spirit of God speaking through the first witnesses.
