Some points one may consider in determining whether they are part of The Army of the Lord.
Cannot Take This Honor
First, no one can take this honor unto themselves:
4 And no man taketh this honour unto himself, but he that is called of God, as was Aaron. (Hebrews 5:4)
Must Feel A Burning Inclination
9 Then I said, I will not make mention of him, nor speak any more in his name. But his word was in mine heart as a burning fire shut up in my bones, and I was weary with forbearing, and I could not stay. (Jeremiah 20:9)
Called of God
1 Listen to me, you islands; hear this, you distant nations: Before I was born the LORD called me; from my mother’s womb he has spoken my name. (Isaiah 49:1 NIV)
5 I knew you before I formed you in your mother’s womb. Before you were born I set you apart and appointed you (Jeremiah 1:5 NLT)
15 But even before I was born, God chose me and called me by his marvelous grace. (Galatians 1:15 NLT)
Knew thee; i.e. took notice of thee; virtually equivalent to selected thee (comp. Genesis 39:6; Amos 3:2; Isaiah 58:3; Psalm 144:3). Observe, the predestination of individuals is a familiar idea in the Old Testament (comp. Isaiah 45:4; Isaiah 49:1; Psalm 139:16). Familiar, too, to the great family of religious reformers. For, as Dean Milman has truly observed, “No Pelagian ever has or ever will work a religious revolution. He who is destined for such a work must have a full conviction that God is acting directly, immediately, consciously, and therefore with irresistible power, upon him and through him.
Has God “separated” you in any way that made you live a holier life? Here are some examples:
1 And the Lord spake unto Moses, saying,
2 Speak unto the children of Israel, and say unto them, When either man or woman shall separate themselves to vow a vow of a Nazarite, to separate themselves unto the Lord:
3 He shall separate himself from wine and strong drink, and shall drink no vinegar of wine, or vinegar of strong drink, neither shall he drink any liquor of grapes, nor eat moist grapes, or dried.
4 All the days of his separation shall he eat nothing that is made of the vine tree, from the kernels even to the husk.
5 All the days of the vow of his separation there shall no razor come upon his head: until the days be fulfilled, in the which he separateth himself unto the Lord, he shall be holy, and shall let the locks of the hair of his head grow. (Numbers 6:1–5)
1 And the children of Israel did evil again in the sight of the Lord; and the Lord delivered them into the hand of the Philistines forty years.
2 And there was a certain man of Zorah, of the family of the Danites, whose name was Manoah; and his wife was barren, and bare not.
3 And the angel of the Lord appeared unto the woman, and said unto her, Behold now, thou art barren, and bearest not: but thou shalt conceive, and bear a son.
4 Now therefore beware, I pray thee, and drink not wine nor strong drink, and eat not any unclean thing:
5 For, lo, thou shalt conceive, and bear a son; and no razor shall come on his head: for the child shall be a Nazarite unto God from the womb: and he shall begin to deliver Israel out of the hand of the Philistines. (Judges 13:1–5)
8 But Daniel purposed in his heart that he would not defile himself with the portion of the king’s meat, nor with the wine which he drank: therefore he requested of the prince of the eunuchs that he might not defile himself.
9 Now God had brought Daniel into favour and tender love with the prince of the eunuchs.
10 And the prince of the eunuchs said unto Daniel, I fear my lord the king, who hath appointed your meat and your drink: for why should he see your faces worse liking than the children which are of your sort? then shall ye make me endanger my head to the king.
11 Then said Daniel to Melzar, whom the prince of the eunuchs had set over Daniel, Hananiah, Mishael, and Azariah,
12 Prove thy servants, I beseech thee, ten days; and let them give us pulse to eat, and water to drink.
13 Then let our countenances be looked upon before thee, and the countenance of the children that eat of the portion of the king’s meat: and as thou seest, deal with thy servants.
14 So he consented to them in this matter, and proved them ten days.
15 And at the end of ten days their countenances appeared fairer and fatter in flesh than all the children which did eat the portion of the king’s meat.
16 Thus Melzar took away the portion of their meat, and the wine that they should drink; and gave them pulse.
17 As for these four children, God gave them knowledge and skill in all learning and wisdom: and Daniel had understanding in all visions and dreams. (Daniel 1:8–17)
John the Baptist
15 For he shall be great in the sight of the Lord, and shall drink neither wine nor strong drink; and he shall be filled with the Holy Ghost, even from his mother’s womb. (Luke 1:15)
Ask yourself, has God done a similar thing in your life?
