The believer in Christ must be prepared to count the cost of following Him and be prepared to suffer the loss of all things for the sake of Him. This is only possible through the power of the Holy Spirit and with his spiritual protection.
The believer is engaged in a constant struggle against the powers of hell. The only way to stand our ground is to do it in the strength of the Lord and the power of His might.
The children of believers are addressed directly in the Bible. they are told to obey their parents certainly going to "in the Lord". We explore the implications of this. Fathers are also addressed. How are we to appropriately parent?
We are justified, adopted, and sanctified in Christ Jesus. Our salvation is secure in Christ but, we are told by our Lord that we are to be careful how we walk because the days are evil.
