Some envision angels like the pictures we see. Winged beings. Cute like the European cherub /cupid style or large angelic white winged forms of man or woman. Angels come in all forms. And we are surrounded by them. God does not sit up there all by himself. He has his crew. Note: so too does the enemy. He has his crew also. The battle of good verses evil is constant. We have to know what to do and how. The guidance is through the word of God. Psalm 91:11 For he will command his angels concerning you to guard you in all your ways"
