King David had great losses and asked the same question.
"Now when David and his men came to Ziklag on the third day, the Amalekites had made a raid against the Negeb and against Ziklag. They had overcome Ziklag and burned it with fire and taken captive the women and all who were in it, both small and great. They killed no one, but carried them off and went their way... And David inquired of the LORD, 'Shall I pursue after this band? Shall I overtake them?' He answered him, 'Pursue, for you shall surely overtake and shall surely rescue.' " - 1 Samuel 30:1-2, 8 ESV
It was not too late.
"David recovered all that the Amalekites had taken, and David rescued his two wives. Nothing was missing, whether small or great, sons or daughters, spoil or anything that had been taken. David brought back all." - 1 Samuel 30:18-19 ESV
What about the people who could not go with him because of weariness.
"But David said, 'You shall not do so, my brothers, with what the LORD has given us. He has preserved us and given into our hand the band that came against us... For as his share is who goes down into the battle, so shall his share be who stays by the baggage. They shall share alike.' " - 1 Samuel 30:23 & 24b ESV
Then David spread the spoils and word of his victory.
"When David came to Ziklag, he sent part of the spoil to his friends, the elders of Judah, saying, 'Here is a present for you from the spoil of the enemies of the LORD.' It was for those in Bethel, in Ramoth of the Negeb, in Jattir, in Aroer, in Siphmoth, in Eshtemoa, in Racal, in the cities of the Jerahmeelites, in the cities of the Kenites, in Hormah, in Bor-ashan, in Athach, in Hebron, for all the places where David and his men had roamed." - 1 Samuel 30:26-31 ESV
David's God given victory blessed people he had met in his travels. In his victory he sent gifts to people who knew him.
I ask you again... Is it too late?
Why don't you ask God and read 1 Samuel 30 a few times and find out.
Oh, and don't worry if not everyone has the strength to go with you... just bless them with your victory when you return.
