Tim - Matthew 5:23,24

"Therefore, if you are offering your gift at the altar and there remember that your brother or sister has something against you, leave your gift there in front of the altar. First go and be reconciled to them; then come and offer your gift. (Matthew 5:23-24 NIV)

Preparation is a process.  It's dangerous to feel settled. Like, "I'm good and I've nothing else to work through" .    The sense of sacrifice should be close to our heart at all times.     God's word on our heart will call out reconcilement .  With everyone.    Obey God no matter how much humiliation it brings to you.   Give up your rights and be a true disciple of Jesus Christ.
