The Spirit Himself bears witness with our spirit that we are children of God, and if children, then heirs—heirs of God and joint heirs with Christ, if indeed we suffer with Him, that we may also be glorified together. For I consider that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us. Romans 8:16–18

The heart is deceitful above all things, and desperately wicked; Who can know it? Jeremiah 17:9

Come to Me, all you who labour and are heavy laden, and I will give you rest. Take My yoke upon you and learn from Me, for I am gentle and lowly in heart, and you will find rest for your souls. Matthew 11:28–29
