You will miss the cross if you fail to understand that God planned the cross out of grace?
This is the counterbalance to the notion that God is only anger and fury against sinners. The marvel is that the righteousness-loving and holy God who is totally self-existent outside of His own creation moved in grace to plan the cross. Above and beyond that, He gave His only begotten Son to be the sacrifice for sin.
So, you need to realise that God planned the cross and provided a sacrifice by giving up His own Son to the cross of Calvary so that guilty sinners, who deserve the wrath of God, will be saved from the flames of hell. Hell is the due desert of rebels to God. The wages of sin is death, so on that cross, the Lord Jesus took our sin and He took our hell for us.
The cross is not just the proof of God's love for the Christian it is also the proof of God's judgment, of hell as the eternal payment for sin.
O Lord, my God, when I in awesome wonder
Consider all the worlds Thy Hands have made
I see the stars, I hear the rolling thunder
Thy power throughout the universe displayed
Then sings my soul, my Saviour God, to Thee
How great Thou art, how great Thou art
Then sings my soul, my Saviour God, to Thee
How great Thou art, how great Thou art
And when I think of God, His Son not sparing
Sent Him to die, I scarce can take it in
That on the Cross, my burden gladly bearing
He bled and died to take away my sin
