Do you believe 2+2=4?

Why do you believe it... that 2+2=4?  What did you say?  Because it is true?

Now, do you believe 2+2=5?   No?  Because you know it is not true?

Then why is it so hard for us to believe this?

John 3:16 – For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.

Why does Jesus speak of the impossibility of a "camel to go through the eye of a needle"? Matt. 19:24  How this verse troubled me!!  Why, God, do you make the way to heaven like an "eye of a needle"??

Because the Gospel is way too good to be true... for our way of thinking.  Holy Scripture tells us this fact:

1 Cor. 2:9 – Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.

So how can we believe it?
Let us go back to the Bible.  Jesus said:

I am the Way, the Truth, and the Life. – John 14:6

Let us go Back To Luther:
1) Luther's Small Catechism, The (Apostle's) Creed, Third Article:

I believe that I cannot by my own reason or strength believe in Jesus Christ, my Lord, or come to Him; but the Holy Ghost has called me by the Gospel, enlightened me with His gifts, sanctified and kept me in the true faith

2) Luther's Large Catechism, Apostle's Creed, Article III, paragraphs 38-39:

For neither you nor I could ever know anything of Christ, or believe on Him, and obtain Him for our Lord, unless it were offered to us and granted to our hearts by the Holy Ghost through the preaching of the Gospel. The work is done and accomplished; for Christ has acquired and gained the treasure for us by His suffering, death, resurrection, etc. But if the work remained concealed so that no one knew of it, then it would be in vain and lost. That this treasure, therefore, might not lie buried, but be appropriated and enjoyed, God has caused the Word to go forth and be proclaimed, in which He gives the Holy Ghost to bring this treasure home and appropriate it to us. 39] Therefore sanctifying is nothing else than bringing us to Christ to receive this good, to which we could not attain of ourselves.

Who then can be saved? (Matt. 19:25)  Jesus answers us:

Matt. 19:26 – ...but with God all things are possible.

I am the Way, the Truth, and the Life. – John 14:6
