1 Timothy 4:8

‘For bodily exercise is profitable for a little, but godliness is profitable for all things, having promise of the life which now is, and of that which is to come.’

For while bodily exercise is profitable, it is only so for a little while, but godliness is profitable in every way. And what is godliness? It is fulfil his responsibility towards God by revealing love out of a pure heart, a good conscience and faith unfeigned (1 Timothy 1:5). And it gives promise of life now and in the age to come (1 Timothy 1:16). The idea here is that those who believe in Him receive eternal life which they can enjoy in the present day (John 5:24; John 10:10; 1 John 5:13), before they move on to enjoy the fullness of eternal life in the age to come.
