I wish to address the misuse of this verse below.
Ephesians 5:18 And be not drunk with wine, wherein is excess; but be filled with the Spirit;
This is a call to be sober: to remain filled with the Spirit as keeping with the fruit of temperance which is self control as opposing drunkenness. This is not a call to seek to be filled supernaturally with the Spirit again. To take that verse to mean that would be going against scripture below, voiding the meaning and promise in those verses.
John 6:35 And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.
To seek to be filled again with the Spirit is to say that Jesus has not kept His promise when you came to and believed in Him, because you still hunger and thirst to be filled.
Matthew 9:17 Neither do men put new wine into old bottles: else the bottles break, and the wine runneth out, and the bottles perish: but they put new wine into new bottles, and both are preserved.
To seek to be filled with the Spirit again is to testify that we are not new bottles, but a broken bottle, unable to hold the new wine. Being filled and thus a new creature in Christ testifies to Jesus being our Saviour.
Luke 11:9 And I say unto you, Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you. 10 For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. 11 If a son shall ask bread of any of you that is a father, will he give him a stone? or if he ask a fish, will he for a fish give him a serpent? 12 Or if he shall ask an egg, will he offer him a scorpion? 13 If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly Father give the Holy Spirit to them that ask him?
To seek to be filled with the Spirit again would make it as though one does have to ask the Father again as if you did not received what was promised the first time when you were saved.
Colossians 2:5 For though I be absent in the flesh, yet am I with you in the spirit, joying and beholding your order, and the stedfastness of your faith in Christ. 6 As ye have therefore received Christ Jesus the Lord, so walk ye in him:7 Rooted and built up in him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving. 8 Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ. 9 For in him dwelleth all the fulness of the Godhead bodily. 10 And ye are complete in him, which is the head of all principality and power:
To seek to be filled with the Spirit again is to deny that you had received Christ to walk in Him when you were saved. If you acknowledge that He is in you, and yet still seek to be filled again with the Spirit, then you are saying that the fulness of the Godhead bodily is not in Christ for us to be complete in Him.
Ephesians 4:4 There is one body, and one Spirit, even as ye are called in one hope of your calling; 5 One Lord, one faith, one baptism, 6 One God and Father of all, who is above all, and through all, and in you all.
To seek another baptism with the Holy Spirit or to be filled with the Spirit again is to give another hope of our calling, testifying to more than one baptism with the Spirit for believers to seek after, moving away from their resting place in Christ Jesus.
1 Corinthians 12:13For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
To seek to be filled with the Spirit again with another baptism is to testify that we are not all baptized by the one Spirit into the one body because there is more than one drink of the one Spirit.
2 Corinthians 11:1Would to God ye could bear with me a little in my folly: and indeed bear with me. 2 For I am jealous over you with godly jealousy: for I have espoused you to one husband, that I may present you as a chaste virgin to Christ. 3 But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ. 4 For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
To seek another Jesus or another Spirit to receive is preaching another gospel as warned against above.
There is only one kind of invitation and only one calling: they all point to the Son in coming to God. It is still emphasized so that believers will not believe every spirit but test them by remembering our faith.
2 Corinthians 13:5 Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
Otherwise, then wayward believers depart from faith and wind up preaching another gospel with signs and lying wonders that does not serve the Lord Jesus Christ nor seek the glory of the Son, but those spirits.
1 Timothy 4:1Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils; 2 Speaking lies in hypocrisy; having their conscience seared with a hot iron;
2 Timothy 2:15 Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth. 16 But shun profane and vain babblings: for they will increase unto more ungodliness.....24 And the servant of the Lord must not strive; but be gentle unto all men, apt to teach, patient, 25 In meekness instructing those that oppose themselves; if God peradventure will give them repentance to the acknowledging of the truth; 26 And that they may recover themselves out of the snare of the devil, who are taken captive by him at his will.
May God cause the increase in reminding every believer of our first love, trusting Him to help us keep our eyes on Him since our Bridegroom will be coming soon.
