There are many "tent" stories in the Bible, but the one that came to me was from Genesis 13 (click to read) when Abraham (then called Abram) and Lot split up. They surveyed the land around them and Abram told Lot to choose and he would take the other. One went to the left and one went to the right. Lot chose the plain of Jordan and pitched his tent towards Sodom. Abram pitched his tent in the land of Canaan. One chose right. One chose wrong. One choice was wise. One chose was unwise. If you don't know the "rest of the story", look up Sodom. What looked to be a good choice from afar, soon became a big problem for Lot and his family.
I love the idea of "Pitch Your Tent" for a ladies' day or ladies' retreat theme. We all must choose where we are going to 'pitch our tent' in our walk of life. We'll either pitch it towards what is good and right or we will pitch it towards what is bad and wrong. Sometimes we start out one way then go to the other, which is great if we were pitching towards the wrong, then come to the right. That's getting back on track.
Not only could the ladies' day theme be with the tents, but also the arrows that are popular now and were used so much in scripture, not always in a good sense, but in how damaging and hurtful they can be. Our words are like arrows Who have sharpened their tongue like a sword (They aimed bitter speech as their arrow...Psalm 64:3 NASV), so the arrow would be a reminder to not be careless with our words. Arrows or darts are also used when referring to Satan, so they would be a huge reminder of how arrows can be thrown at us and how to be prepared to extinguish them. (I don't care for the idea of using them for event decor if going in that direction. Personally I don't want to make something "pretty/cute" that's ugly sin. You probably don't, either!) "...in addition to all, taking up the shield of faith with which you will be able to extinguish all the flaming arrows of the evil one. Ephesians 6:16.
One scripture passage refers to children, so it would especially be beneficial for a younger mom's lesson or class.
Behold, children are a gift of the LORD, The fruit of the womb is a reward. Like arrows in the hand of a warrior, So are the children of one's youth. How blessed is the man whose quiver is full of them; They will not be ashamed When they speak with their enemies in the gate. Psalm 127:3-5
Where are you pitching your tent today? Choose the good. Choose well.
