Do you believe God has a plan for each of us apart from us learning to love one another?

This is ..oddly.. hard for me to answer.
My initial response is, yes. Of course he does. God creates nothing that does not have a purpose. He created us to love and love him in return.
And then that whole sin thing happened.
And through corruption our intended purpose is grander - as in there are many more facets to it leading to the same end as was planned from the beginning.
To the exile of Jerusalem God said, “ For I know the plans I have for you,” declares the Lord, “plans to prosper you and not to harm you, plans to give you hope and a future” I like to assume that is something he has for all of us who have chosen to seek the lord with all of our hearts as well. And according to romans, all things work together for good. So My assumption is that wether we are opening ourselves to the plans of our lord, or not - there is a plan for our lives.
But, we don’t always listen. And when we don’t seek God, that plan becomes terribly corrupted.
so, still yes. There is a plan. But I do think it is important that we ask and seek the path the lord provides and trust that he will lead us down it. Because goodness knows, there is no clear exact map for what we ought to do in our lives.
I’ve heard that our plan has to do with our talents, or gifts. What we are good at. I don’t know if there is any truth in that though.
