Moses was educated in all the wisdom of the Egyptians and was powerful in speech and action.”Acts 7:22
Moses is said to have been powerful in speech and action yet when asked by God to speak to Pharaoh he said “Moses said to the Lord, “Pardon your servant, Lord. I have never been eloquent, neither in the past nor since you have spoken to your servant. I am slow of speech and tongue.” Exodus 4:10. Is this a contradiction? I do t think so.
Whatever task we have to undertake we must remember “....that we are competent in ourselves to claim anything for ourselves, but our competence comes from God.” 2 Cor 3:5. God can use anyone except those full of themselves. b. When you recognize your inabilities to be what God desires you to be, you recognize that you need Him who is your sufficiency to work through you. Paul wrote to the Galatians:
"If a man thinks that he is something, when he is nothing, he deceived himself." Gal 6:3. Let God be your strength and you sufficiency.trust in Him and lean not on your understanding. Your deficiency leaves room for God's sufficiency.
