Because He died for me in my place. He imputed His righteousness to me, not by my efforts but His free gift, grace.
All I did was believe He is God, that He lived sinless, died and rose again and by believing this..past tense.. I have everlasting life.
John 3:16, 3:36, 5:24, 6:40
Ephesians 2:8-9
Romans 5:8, Romans 10:9-10
I agree. Horatius Bonar wrote a hymn that says:
Not what my hands have done
Can save my guilty soul;
Not what my toiling flesh hath borne
Can make my spirit whole.
2 Not what I feel or do
Can give me peace with God;
Not all my prayers and sighs and tears
Can bear my awful load.
3 Thy work alone O Christ,
Can ease this weight of sin;
Thy blood alone, O Lamb of God,
Can give me peace within.
4 Thy love to me, O God,
Not mine, O Lord, to Thee,
Can rid me of this dark unrest,
And set my spirit free.
5 Thy grace alone, O God
To me can pardon speak;
Thy power alone, O Son of God,
Can this sore bondage break.
6 I bless the Christ of God;
I rest on love divine;
And with unfaltering lip and heart,
I call this Saviour mine.
