if you confess with your mouth "Jesus is Lord" and believe in your heart that God raised Him from the dead, you will be saved. With the heart one believes, resulting in righteousness and with the mouth one confesses, resulting in salvation. Now the scriptures says, NO ONE WHO BELIEVES ON HIM WILL BE PUT TO SHANE.
God's amazing promise is that if we believe, confess and put out trust in Him, we will not be put to shame. So many things in our lives we trust in and put our confidence, let us down but God's promise is He will never let us be put to shame.
Which doesn't mean life wont be hard or filled with troubles but trusting in God and His plan some how gives us a peace we can not get from stuff or things.
In the end, on the last day of time those who put their trust and hope in Christ will not be put to shame.
I'm trusting Christ are you?
