The 'Me' in John 14:14 is not in error.
What is in error is your attempt to use Matthew 6:9 to show Jesus isn't to be prayed to. This is foolish. He is the proper recipient of prayer (Acts 1:24-26; 7:59-60; Romans 10:12-14; 1 Corinthians 1:2; etc.). Furthermore, nowhere in Matthew 6:9 does the word 'only' appear. It doesn't teach we are to pray only to the Father. That is your misunderstanding.
Here are the Scriptures which you referenced. None of these mentions Christians praying to Jesus.
Acts 1:24-26 (VW)
24 And they prayed and said, You, O Lord, who know the hearts of all, show which of these two You have chosen
25 to take part in this ministry and apostleship which Judas abandoned, that he might go to his own place.
26 And they cast their lots, and the lot fell on Matthias. And he was numbered with the eleven apostles.
Praying to the "Lord" is something I do often, but it doesn't mean specifically praying to Jesus.
Acts 7:55-60 (WEB)
55 But he, being full of the Holy Spirit, looked up steadfastly into heaven, and saw the glory of God, and Jesus standing on the right hand of God,
56 and said, “Behold, I see the heavens opened, and the Son of Man standing at the right hand of God!”
57 But they cried out with a loud voice, and stopped their ears, and rushed at him with one accord.
58 They threw him out of the city, and stoned him. The witnesses placed their garments at the feet of a young man named Saul.
59 They stoned Stephen as he called out, saying, “Lord Jesus, receive my spirit!”
60 He kneeled down, and cried with a loud voice, “Lord, don’t hold this sin against them!” When he had said this, he fell asleep.
Stephen actually saw Jesus and spoke to him. If you call that praying, then whenever the disciples spoke to Jesus, during his earthly ministry, they were praying.
Rom. 10:12,13 (WEB)
12 For there is no distinction between Jew and Greek; for the same Lord is Lord of all, and is rich to all who call on him.
13 For, “Whoever will call on the name of the Lord will be saved.”
This is for the unsaved, calling out for the Lord to save them. I was referring to how Christians are told to pray.
1 Cor. 1:2 (VW) to the church of God which is in Corinth, to those who are sanctified in Christ Jesus, called saints, with all who in every place call on the name of Jesus Christ our Lord, both theirs and ours:
We pray to the Father, in the name of our Lord Jesus Christ.
