Hebrews 11:1-3,6,13,14, 16
Now faith is the substance of things hoped for, the evidence of things not seen. For by it the elders obtained a good report. Through faith we understand that the worlds were formed by the word of God, so that things which are seen were not made of things which do appear. ...without faith it is impossible to please Him: for He that cometh to God must believe that He is, and that He is a Rewarder of them that diligently seek Him. ...These [Abraham, Isaac and Jacob] all died in faith, not having received the promises, but having seen them afar off, and were persuaded of them, and embraced them, and confessed that they were strangers and pilgrims on the earth. For they that say such things declare plainly that they seek a country. ...But now they seek a better country, that is, an heavenly: wherefore God is not ashamed to be called their God: for He hath prepared for them a city.
1st Peter 2:11, 12
Dearly beloved, I beseech you as strangers and pilgrims, abstain from fleshly lusts, which war against the soul; having your conversation honest among the Gentiles: that, whereas they speak against you as evildoers, they may by your good works, which they shall behold, glorify God in the day of visitation.
