He Who Is The Beginning and The Ending

“John to the seven churches which are in Asia: Grace be unto you, and peace, from Him which is, and which was, and which is to come; and from the seven Spirits which are before His throne; and from Jesus Christ, the faithful witness, the first begotten of the dead, and the Prince of the kings of the earth. Unto Him that loved us, and washed us from our sins in His own blood, and hath made us kings and priests unto God and His Father; to Him be glory and dominion for ever and ever. Amen.
Behold, He cometh with clouds; and every eye shall see Him, and they which pierced Him: and all kindreds of the earth shall wail because of Him. Even so, Amen.
‘I am Alpha and Omega, the beginning and the ending,’ saith the Lord, which is, and which was, and which is to come, the Almighty.’”  Revelation 1:4-8  (KJB)

Instruction for Pastors

“For I have not shunned to declare unto you all the counsel of God. Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which He hath purchased with His own blood.
For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.  Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them.  Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears.  And now, brethren, I commend you to God, and to the word of his grace, which is able to build you up, and to give you an inheritance among all them which are sanctified.  I have coveted no man’s silver, or gold, or apparel.  Yea, ye yourselves know, that these hands have ministered unto my necessities, and to them that were with me.  I have shewed you all things, how that so labouring ye ought to support the weak, and to remember the words of the Lord Jesus, how He said, ‘It is more blessed to give than to receive.’” Acts 20:27-35
