""Rejoice in the Lord always; again I will say, rejoice. ... And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus." Philippians 4:4-7 All of us will face troubles in this life. We get anxious about what will happen because we're not in control. This is common to all of us, however we can have the peace of God. * When a person living with another of the same sex receives the Holy Spirit into his life, should he abstain from that kind of lifestyle? * Does God bless Christians who enter the military for the sake of defending their nation? * 1 Corinthians 9:24-27 Can you help me understand these passages please?
