You can be committed to Church but not committed to Christ, but you cannot be committed to Christ and not committed to church.
Put your shoulders back, hold your head up high knowing that the same power that raised Christ from the dead lives on the inside of you.
We were old sinners - but when we came to Christ we are not sinners anymore.
Salvation and Christ's love is a gift. You don't earn it. You've got to receive that gift.
