To believe in Jesus means to believe He is The Son Of God and one with God, that He was born by a virgin, was crucified, died and was buried, and that He arose on the third day as stated in The Holy Bible. It means to commit to live by His ways which scriptures prescribe, not to deny Him in any way before men, and to live exclusively for Him. The person who does this shall not be ashamed of his/her end. His/her expectations/desires shall not be cut off.
The question now is, do you really believe? If you do, then you can say like David…
I have stuck unto thy testimonies: O LORD, put me not to shame. Psalm-119:31
For your shame ye shall have double; and for confusion they/you shall rejoice in their/your portion: therefore in their/your land they/you shall possess the double: everlasting joy shall be unto them/you. Isaiah-61:7
You and your added by me for emphasis.
