As believers, our expectant, certain, hope looks forward to the things that the Word of God promises are to come for us. That hope includes eternal life with our Lord Jesus in a heaven that contains wonders and beauty beyond anything that we can imagine or know about on this earth.
1 Cor 2:9
9 But as it is written, 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.
KJV
In times of our deepest sorrow, this is our certain hope.
In times of our greatest tragedy, this is our certain hope.
In times of our greatest loss, this is our certain hope.
When death comes for us, this is our certain hope.
That Jesus Christ is coming again and that He has prepared a place in heaven for us.
John 14:1-3
1 Let not your heart be troubled: ye believe in God, believe also in me.
2 In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you.
3 And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.
KJV
This is our certain hope that we base our faith on. This is our certain hope of the things that are to come.
