If someone need something to "connect" with God with, He tells us to meditate on His word. So to help them through the day, might I suggest putting Bible memory verses in their wallet.
Psa_119:11 I have stored up your word in my heart, that I might not sin against you.
Excellent advice.
Also: I recommend a picture of Christ. Or a crucifix, to connect us with His sorrowful passion.
