First thing’s first. Know the Word of God for yourself then you can share it with others.
Read: Ezekiel 3:10-11
10 Then he added, “Son of man, let all my words sink deep into your own heart first. Listen to them carefully for yourself. 11 Then go to your people in exile and say to them, ‘This is what the Sovereign Lord says!’ Do this whether they listen to you or not.”
