SEE JESUS!!
You should never judge the power and might of who God is according to a person's situation..God is the same yesterday today and forever..people sometimes get weak change and fall short..GOD IS!!!!!! Even though the word tells us to not grow weary in doing well..sometimes flesh rise up..and yes Christians are the only tangible being in order to see God here on earth..however, you must look to Jesus through the spirit realm to get a better understanding of who He is..people are not perfect but God is..therefore you have to trust Him for self not trust in humans (per se) that claim to live for Him..work out your own and leave it to Him to deal with others..He said He is always there even unto the end of the world..shouldn't focus on the downfall..if anything pray to Him for other's come up ~{LEFTBEHIND4PURPOSE}~
