The difficulties of the world are real. How can a saved person find peace among the chaos? God gave the saved to Christ before the foundations of the earth. This is the promise for God's people. Christ knows his sheep by name and he will gather his sheep and lead them home. The environment you face on a daily basis will not lift you up. John 6:37 says "All that the Father gives me shall come to me; and him that cometh to me I will in no wise cast out". John 39 promises "And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day." Fix your eyes upon heaven and Christ will raise us up in the last day.
