two unsaved co-workers

Hey everyone, right now I would like to ask for prayers on behalf of two unsaved co-workers I tried to introduce to Jesus recently. At first glance it didn´t go too well but I think I learned quite a bit about the stumbling blocks they are facing. The first one – name is Nina – is apparently holding a grudge against God for allowing nice people including family members to suffer and die in this world. The second one – name is Stefanie – just seems to be way too focused on superficial and material things to really be receptive to the Gospel. Thx for any support in Christ! God bless you all
