What are the consequences of justification (Rom. 5:1)?
We have peace with God. This is tremendous. No issues between God and us! Nothing that separates. Unbelievers are at enmity with God and need to be reconciled with Him. For a believer there is peace (not only a promise that he will have peace with God, but he has it already!). And there is much more: read Romans 5:1-11 to see the wonderful consequences of justification and peace with God.
