2 Peter 1:3 According as HIS DIVINE POWER hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue:
There is no other source of mortal or eternal life. Salvation is an intrusion into our hearts and lives by the God who loves us and is a wonderful intruder we always ought to love and trust.
Genesis 2:7 And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
Matthew 28:18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
John 10:27 My sheep hear my voice, and I know them, and they follow me: 28 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
John 15:5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for WITHOUT ME YE CAN DO NOTHING.
Acts 15:7 And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, ye know how that a good while ago God made choice among us, that the Gentiles by my mouth should hear the word of the gospel, and believe. 8 And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us; 9 And put no difference between us and them, purifying their hearts by faith.
Our Creator is the only one who can purify our hearts.
Ephesians 2:10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
A saved soul is the work and workmanship of God alone and the good works Christians are to walk in are ordained by God.
