6 If you put these things before the brothers, you will be a good servant of Christ Jesus, being trained in the words of the faith and of the good doctrine that you have followed. 7Have nothing to do with irreverent, silly myths. Rather train yourself for godliness; 8for while bodily training is of some value, godliness is of value in every way, as it holds promise for the present life and also for the life to come. 9The saying is trustworthy and deserving of full acceptance. 10For to this end we toil and strive, because we have our hope set on the living God, who is the Savior of all people, especially of those who believe.In these verses Paul talks with Timothy about how good it is to train yourself in godliness.
That just as a person trains their body, one must train themselves in Godliness and doing so will stand a person in better stead. Why? Because training yourself in godliness not only benefits you in this life, but it also benefits you in the life to come.
Just as when a person is in physical training there are things they must avoid, so too with training in godliness. When training in the latter one must avoid all types of silly myths and false teachings. One must look for good doctrine and sound teaching.
Because our hope as believers is set on God. God who is the Saviour of the world, particularly for those who believe.
