13 It is written: “I believed; therefore I have spoken.” Since we have that same spirit of faith, we also believe and therefore speak, 14 because we know that the one who raised the Lord Jesus from the dead will also raise us with Jesus and present us with you to himself. 15 All this is for your benefit, so that the grace that is reaching more and more people may cause thanksgiving to overflow to the glory of God.– 2 Cor. 4:13-15 NIV
“I believed; therefore I have spoken.” is a reference to Psalm 116 (KJV). The Psalmist is referencing a time when God had delivered him from death either physically and/or spiritually. Paul says that we who have this same spirit of faith can have confidence, believe and therefore speak of the saving grace of Jesus, our Savior and Lord. We know that the same resurrection power that raised Jesus from the dead has already raised us from spiritual death. Since we know this, we can be confident of the hope we have that one day He will raise us from the dead physically. We will die as mortals and be raised as immortals clothed in the righteousness of Jesus Christ. If we were not changed into His image, we would not be able to stand before God. This knowledge of God’s amazing grace and our hope for the future should cause us to continually give thanks and explode with joy and praise that overflows to the glory of God. Through this power, we can be over-comers and participants in the abundant life with which God wants to bless us. Our rejoicing will bring more and more people to the Kingdom!

Bless the Lord, O my soul! — Psalm 104:1
