'When the Israelites were at Rephidim, they were attacked by the Amalekites. So Moses told Joshua, “Have some men ready to attack the Amalekites tomorrow. I will stand on a hilltop, holding this walking stick that has the power of God.” Joshua led the attack as Moses had commanded, while Moses, Aaron, and Hur stood on the hilltop. The Israelites out-fought the Amalekites as long as Moses held up his arms, but they started losing whenever he lowered them. After a while, his arms were so tired that Aaron and Hur got a rock for him to sit on. Then they stood beside him and supported his arms in the same position until sunset. '
This whole scripture talks about testifying in the presence of others .Some may not believe, but doing what others say is impossible and witnessing it is HIM can be miraculous. Even when others had to hold Moses’ hands up he still attended to what God recommended.
My job is to testify-to hear God and follow His lead. He will make a way for others to SEE his work. Our job is not to point out his work, but to DO his work. Others will see the witness in that.
Just because someone does not invite God into their lives, they may allow HIM because of other’s testimony.
