Exodus:35:29- The children of Israel brought a willing offering unto the LORD...
I have been in meetings where people gave under compulsion not because they were willing. The use of gimmicks to make people part away with their monies and valuables has pervaded many charismatic circles.
The word of God remains a standard for us all no matter how a preacher may make us feel. There are givers that don't get blessed because they failed to give from a willing heart. When you sow a large seed under compulsion&pressure, its no longer a spiritual exercise.
For your seed sowing and offerings to be acceptable in heaven, let God lead you or better still, decide in your heart what you want to give. God respects your decision in such matters.
Stop running to circles where your seed won't count in heaven, sow willingly on the right ground.
Father, I receive grace to give from a willing heart In Jesus Name.
