It’s not what I can do, or what I have done.
It’s what HE DID for me.
1 Corinthians 15:1-4
Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
4 And that he was buried, and that he rose again the third day according to the scriptures:
He paid my sin debt in full.
He died for my sins (all of them)
He was buried
And He rose from the dead on the third day for my justification.
There is no greater gift. A gift. A gift which cannot be bought, a gift given freely.
A gift to save your eternal soul.
Realise there is nothing you can do to save yourself. Only God saves.
