If we stand our ground, we will see the victory of the Lord, for He will fight for us (Ex 14:14). Moses made this promise before the Lord rescued the chosen people by drowning the Egyptians in the Red Sea. This is a symbol of Baptism.
When we stand on the ground of our Baptism, we will see the Lord's victory. We must stand on the fact that through Baptism we are in Christ. Therefore, we are new creations, children of God the Father, redeemed by the blood of Jesus, temples of the Holy Spirit, and members of the Church, the body of Christ.
If we stand on the ground of our own power, plans, or importance, we will not see the Lord's victory. Our own basis for victory is groundless.
God's victory comes to those standing on the right ground: God's ground. Many Christians have disregarded God's "no trespassing" signs and stand on the wrong ground. When they repent, get back where they belong, and stand there, they will see God's victory. Back to Baptism. Forward to victory (see Ex 14:15).
