Mouth n heart

But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach;

 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.

 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. 

For the scripture saith, Whosoever believeth on him shall not be ashamed.

 For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him. 

For whosoever shall call upon the name of the Lord shall be saved.
Romans 10:8‭-‬13 KJV

Let your mouth and your heart unite in worshipping God. Don't say what your heart does not believe. Confess the word that is your mouth and in your heart. You confess Jesus with your mouth and believe in your heart that God raised him from the dead and you will be saved. You will not be ashamed.

Anyone can call on the name of the Lord and be saved. Speak words of faith for the words we speak become the house we live in. Keep confessing the word even if the situation remains same. Your faith becomes stronger and God is pleased.
