Here are two songs that mean something to me and my walk with the Lord.
"I'm never gonna look back, I've made up my mind
I've got too much invested
To lose my time
Through the rivers, and over the mountains and plains
I'm never gonna look back till I reach heavens gates."
and
"When I look back, and see,
Where Jesus brought me from
It's a mighty long way, from where I used to be.
For my soul, it was so lost in sin and misery
And I'm singing this song,
'Cause I know where, He brought me from."
I think the two can co-exist.
Remembering the pit we were dug from...
Isaiah 51:1
Psalm 40:2
He brought me up also out of an horrible pit, out of the miry clay, and set my feet upon a rock, and established my goings.
And
Philippians 3:13
Brethren, I count not myself to have apprehended: but this one thing I do, forgetting those things which are behind, and reaching forth unto those things which are before
I think there are those who remember where they were brought from is a great strength to them.. and those who are much better served not looking back.
You find the one that serves you best and stick with that mentality.
My father... when he looks back he has Joy because he knows where God has brought him. My husband, prefers not to think on his past much at all.
I think it matters as well, how far along on the journey you are. The further you get from that pit, the less hold it has if you look back and regard it.
But like Lot's wife... we shouldn't look back and miss the old life.. so if you're tempted to look back and miss it... "don't look Etheeeeellll"
These are my thoughts anyway.
