“[…] God is not ashamed of them, to be called on as their God […].”
This verse leads me to wonder if I sometimes conduct myself in a way that would embarrass God because I carry his name.
Psalm 15 lists some qualities expected of friends of God: showing integrity, being honest, honoring those who deserve it, rejecting gossip, keeping our word, kindly sharing material things, and rejecting corruption.
God’s Word tells us the importance of believing in him to the point that we do not doubt his individual love for us. (Heb. 11:6)
Other qualities include being willing to make an honest living, and to not entertain ourselves with violence or other activities he hates. (Is. 33:15,16)
And while we may feel unworthy of being called God’s friend, we need humility to keep trying to meet his standards. (Ps. 16:7)
