We must realize that Christ brings us into His kingdom by dying for us, by bearing our sins in His own body, by being made the Lamb of God for us; that He bears our punishment, and that He is our only way of deliverance and salvation. You believe it and you say:
Just as I am, without one plea
But that Thy blood was shed for me,
And that Thou bid’st me come to Thee,
O Lamb of God, I come.
In other words, it means that you make an absolute, total surrender; you cast yourself entirely into His hands. You deny yourself, you take up your cross, and you follow Him. And if you do these things, the kingdom of God is within you. You have entered the kingdom, and the kingdom has entered you; you see that He is everything to you, and you are nothing. You see that Christ is “the Alpha and the Omega, the beginning and the end.” “He is the lily of the valley: the bright and morning star. He is the fairest of ten thousand to my soul.”
Thou, O Christ, art all I want;
More than all in Thee I ﬁnd.
You just give yourself to Him and acknowledge Him as the Son of God and your personal Savior and Lord. Your one desire is to know Him, to be near Him, and to follow Him in order that you may be in glory with Him in the ﬁnal regeneration when He comes at the end of time.
