Judges 6:12 NASB
[12]The angel of the Lord appeared to him and said to him, "The Lord is with you, O valiant warrior."
In the above text Gideon is visited by an angel of Lord then given a sign,but goes on to ask for more signs in the following texts
Judges 6:37 NASB
[37]behold, I will put a fleece of wool on the threshing floor. If there is dew on the fleece only, and it is dry on all the ground, then I will know that You will deliver Israel through me, as You have spoken
Judges 6:39 NASB
[39]Then Gideon said to God, "Do not let Your anger burn against me that I may speak once more; please let me make a test once more with the fleece, let it now be dry only on the fleece, and let there be dew on all the ground."
Could this be a sign of diffidence & distrust in God?
