…and unto them that look for Him shall He appear the second time without sin unto salvation. – Hebrews 9:28

Notice that this appearing and this salvation will chiefly belong to those who look for Him...The text says, “Unto them that look for Him shall He appear a second time without sin unto salvation.” How many here are looking for our Lord’s second coming? I am afraid if conscience hath her perfect work many will have to say, “I am afraid I am not among the number.” I will tell you what it is to look for that second appearing. It is to love the Lord Jesus, to love Him so that you long for Him as a bride longeth for her husband. Why are His chariots so long in coming? Come quickly, Lord Jesus! Strong love hates separation, it pines for union. It cries, “Come, Lord! Come, Lord!” Longing follows on the heels of loving. To look for His coming is to prepare for Him. If I were asked to visit you to-morrow evening, I am sure you would make some preparations for my call-even for one so common-place as myself. You would prepare, because you would welcome me… When we expect our Lord to come, we shall be concerned to have everything ready for Him. I sometimes see the great gates open in front of the larger houses in the suburbs; and it means that they are expecting company. Keep the great gates of your soul always open, expecting your Lord to come…Do not say, “The Lord will not yet come, and therefore I shall make my plans irrespective of Him for the next twenty or thirty years.” You may not be here in the next twenty or thirty minutes, or, if you are, your Lord may be here also. He cometh; He is on the road; He started long ago, and He sent on a herald before Him to cry, “Behold, I come quickly.” He has been coming quickly over the mountains of division ever since; and He must be here soon. If you look for His appearing you will be found in an attitude of one who waits and watches, that when his Lord cometh he may meet Him with joy. Christ is coming, I must not sin: Christ is coming, I must not be rooted to the world. Are you thus expecting Him? ~ C.H. Spurgeon
