As our FATHER, YAHWEH, told Moses then, HE says to us now, don’t worry about your speech impediment, or any inadequacies you feel about yourself. Rather trust in HIM to use you as you are to perform HIS signs and wonders in this earth. We are made perfect through HIS SON and perform HIS works by HIS SPIRIT’s power through us. And to be clear, no human is perfect. Our YAH’s strength is made perfect in our weaknesses. So lean on HIM and not your own abilities. For the power to perform any wonders comes from HIM alone.
Exodus 4:10-17 Then Moses said to the Lord, “O my Lord, I am not eloquent, neither before nor since You have spoken to Your servant; but I am slow of speech and slow of tongue.” So the Lord said to him, “Who has made man’s mouth? Or who makes the mute, the deaf, the seeing, or the blind? Have not I, the Lord? Now therefore, go, and I will be with your mouth and teach you what you shall say.” But he said, “O my Lord, please send by the hand of whomever else You may send.” So the anger of the Lord was kindled against Moses, and He said: “Is not Aaron the Levite your brother? I know that he can speak well. And look, he is also coming out to meet you. When he sees you, he will be glad in his heart. Now you shall speak to him and put the words in his mouth. And I will be with your mouth and with his mouth, and I will teach you what you shall do. So he shall be your spokesman to the people. And he himself shall be as a mouth for you, and you shall be to him as God. And you shall take this rod in your hand, with which you shall do the signs.”https://bible.com/bible/114/exo.4.10-17.NKJV
Zechariah 4:6-7 So he answered and said to me: “This is the word of the Lord to Zerubbabel: ‘Not by might nor by power, but by My Spirit,’ Says the Lord of hosts. ‘Who are you, O great mountain? Before Zerubbabel you shall become a plain! And he shall bring forth the capstone With shouts of “Grace, grace to it!” ’ ”https://bible.com/bible/114/zec.4.6-7.NKJV
I Corinthians 12:1-11 Now concerning spiritual gifts, brethren, I do not want you to be ignorant: You know that you were Gentiles, carried away to these dumb idols, however you were led. Therefore I make known to you that no one speaking by the Spirit of God calls Jesus accursed, and no one can say that Jesus is Lord except by the Holy Spirit. There are diversities of gifts, but the same Spirit. There are differences of ministries, but the same Lord. And there are diversities of activities, but it is the same God who works all in all. But the manifestation of the Spirit is given to each one for the profit of all: for to one is given the word of wisdom through the Spirit, to another the word of knowledge through the same Spirit, to another faith by the same Spirit, to another gifts of healings by the same Spirit, to another the working of miracles, to another prophecy, to another discerning of spirits, to another different kinds of tongues, to another the interpretation of tongues. But one and the same Spirit works all these things, distributing to each one individually as He wills.https://bible.com/bible/114/1co.12.1-11.NKJV
II Corinthians 12:7-10 And lest I should be exalted above measure by the abundance of the revelations, a thorn in the flesh was given to me, a messenger of Satan to buffet me, lest I be exalted above measure. Concerning this thing I pleaded with the Lord three times that it might depart from me. And He said to me, “My grace is sufficient for you, for My strength is made perfect in weakness.” Therefore most gladly I will rather boast in my infirmities, that the power of Christ may rest upon me. Therefore I take pleasure in infirmities, in reproaches, in needs, in persecutions, in distresses, for Christ’s sake. For when I am weak, then I am strong.https://bible.com/bible/114/2co.12.7-10.NKJV
