Thirsting Souls Bible Teaching

(Tit 2:1) “But speak thou the things which become sound doctrine: (2) That the aged men be sober (circumspect), grave (honorable), temperate (Spirit controlled), sound in faith (doctrinally grounded), in charity (sacrificial love), in patience (trusting thus not anxious).”  As you can see, every believer is to be growing in the grace of God. Those who are (retirement age?) men should be striving to meet this level of spirituality. How do we obtain: prayer and submission to God?
