Salvation changes everything.

The master theme of the Christian gospel is salvation. Salvation is a picture-word of wide application that expresses the idea of rescue from jeopardy and misery into a state of safety. The gospel proclaims that then God who saved Israel from Egypt, Jonah from the fish's belly, the psalmist from death, and the soldiers from drowning (Exod 15:2; Jon 2:9; Ps 116:6; Acts 27:3), saves all who trust Christ from sin and sin's consequences
As these earthly deliverances were wholly God's work, and not instances of people saving themselves with God's help, so it is with salvation from sin and death... What are believers saved from? From their former position under the wrath of God, the dominion of sin, and the power of death (Rom 1:18; 3:9; 5:21); from their natual condition of being mastered by the world, the fles, and the devil (John 8:23-24; Rom 8:7-8; 1 John 5:19); from the fears that a sinful life engenders... and from the many vicious habits that were part of it...
~J.I Packer - Concise Theology; p146-147

And how are we saved? Only through the work of Jesus on the cross. It's not Jesus helping us to be better people... it's Jesus substituting Himself where we should be... it's Him taking the wrath that we deserve for all those things we're being saved from.

By Jesus paying that price our old lives are replaced, and our new life is bathed in hope and grace. How does that affect your attitude today!?
