Leave your gift at the altar and go.
The heart of a servant holds the sensitivity of the Spirit. Even in the smallest details, we can never object to the Holy Spirit. If you are not reconciled with someone today, you must repent. Jesus does not say hold the gift and wait. Jesus says for you to go because it is not a matter of your rights. A true Christian waives his own rights and submits to the righteousness of Christ. Decide to be dedicated to serving others and rejoice in the restraint of the Holy Spirit.
Pray for a heart of reconciliation.
