In the journey of destiny, not all the people you meet are part of your vision and as a matter of fact, God gives you per time people according to His pre determinate plan for the fulfilment of that assignment, they might be for LIFE and they might be for a SEASON.
Carrying other LOADS will weigh you down, it becomes an excess BURDEN and those WEIGHT must have to be SHED per time. Whether you like it or not, if you must FULFIL your CALLING, not everyone is meant to stay..
Either they LEAVE or you LEAVE, once that happens, your BURDEN becomes light and you are set to move at God's PACE for your RACE. Don't let it WEIGH you DOWN when those you love most leave...
Some things are IMPORTANT but not NECESSARY and only those NECESSARY, will stay. God will only keep those NECESSARY to serve their purpose for the ACCOMPLISHMENT of that ASSIGNMENT.

Abram, "LEAVE your KINDRED', but he took LOT along and it almost became a THORN in his flesh not until they had to
JOURNEY APART. Then was he (Abram) able to SEE; all these while he was perhaps busy SEEING LOT and as his nature of (HOSPITALITY), seeking Lot's comfort.
(I presume).
