Romans 8:18

For. reckon that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed to us-ward. "I reckon" -'I consider' (RSV); 'It implies reasoning, "I judge after calculation made".' (Vincent p. 92).. am convinced. 'Denotes no doubt, but confident assurance'. (Erdman p. 99)

Here is where many fail. It's not because their own sufferings are worse or more difficult than others (1 Corinthians 10:23), but it is because they are NOT convinced that heaven is far more than worth the suffering of the present time. They don't need an easier life, rather they need greater faith.

"sufferings of this present time" -in the context the suffering that comes upon one because of his loyalty to Christ. (Acts 14:22)

"not worthy to be compared" -Paul dismisses the suffering of the present time because he has his eye on incomparable glory. He isn't saying that suffering isn't real (The Christian Science view that suffering is illusory, is just plain ungodly, for that means that Jesus' suffering on the cross was only an illusion.) Neither is he saying that suffering is 'no big deal'.

"with the glory which shall be revealed to us-ward" -such future glory is 'certain' for the faithful. (Matthew 5:12 '..for your reward in heaven is great'; 1 Peter 1:4; 2 Corinthians 4:17 'glory far beyond all comparison')
