And you hath He quickened, who were dead in trespasses and sins – Ephesians 2:1

A man ought to believe in Jesus: it is his duty to receive Him whom God has set forth to be a propitiation for sins. But man will not believe in Jesus; he prefers anything to faith in his Redeemer. Unless the Spirit of God convinces the judgment, and constrains the will, man has no heart to believe in Jesus unto eternal life. I ask any saved man to look back upon his own conversion, and explain how it came about. You turned to Christ, and believed in His name: these were your own acts and deeds. But what caused you thus to turn? What sacred force was that which turned you from sin to righteousness? Do you attribute this singular renewal to the existence of a something better in you than has been yet discovered in your unconverted neighbour? No, you confess that you might have been what he now is if it had not been that there was a potent something which touched the spring of your will, enlightened your understanding, and guided you to the foot of the cross. Gratefully we confess the fact; it must be so. Salvation by grace, through faith, is not of ourselves, and none of us would dream of taking any honour to ourselves from our conversion, or from any gracious effect which has flowed from the first divine cause.

If my Lord Jesus gives you salvation at this moment, you have it, and you have it forever. He will never take it back again; and if He does not take it from you, who can? If He saves you now through faith, you are saved-so saved that you shall never perish, neither shall any pluck you out of His hand. May it be so with every one of us! Amen. ~ C.H. Spurgeon
