The answer to these questions is an emphatic NO! Nothing can separate Christ from us once we ask Him into our hearts. But also realize that troubles are NOT an indication that God is withholding His love for us. Calamity, persecution, hunger, destitution, danger, and death are all a result of living in a broken world.
Can anything ever separate us from Christ’s love? Does it mean he no longer loves us if we have trouble or calamity, or are persecuted, or hungry, or destitute, or in danger, or threatened with death?
~ Romans 8:35 [NLT]
