The single most important lesson I learned came from Henry Blackabee. Through him I learned to stand still, be quiet, look and listen to see what God has going on. Then move closer to God and join in in what He is doing.
And bring others in with you. But at a speed they can follow. Some are hungry and want a lot of information and encouragment.
Some get mad. Better to leave them alone or they just get madder.
One speed doesn't work for everyone...
Also, it doesn't all depend on us. The person must be convicted by the Holy Spirit. We have responsibility, but full responsibility cannot fall on us. It would be too big of a burden to bear, and might even discourage us for future witnessing.
