A very good Scripture to meditate on until it lights up on the inside of you is Isaiah 54:17 AMP:
17 But no weapon that is formed against you shall prosper, and every tongue that shall rise against you in judgment you shall show to be in the wrong. This [peace, righteousness, security, triumph over opposition] is the heritage of the servants of the Lord [those in whom the ideal Servant of the Lord is reproduced]; this is the righteousness or the vindication which they obtain from Me [this is that which I impart to them as their justification], says the Lord. AMP
Do you believe this? You MUST if you are ever going to go on with the things of God with any effectiveness! Once you really "get" this one, then begin to meditate on this from Romans 8:37-39:
37 Yet amid all these things we are more than conquerors and gain a surpassing victory through Him Who loved us. 38 For I am persuaded beyond doubt (am sure) that neither death nor life, nor angels nor principalities, nor things impending and threatening nor things to come, nor powers, 39 Nor height nor depth, nor anything else in all creation will be able to separate us from the love of God which is in Christ Jesus our Lord. AMP
There is not a thing you can't accomplish or a test or trial that you can't gain the victory over, IF you will meditate on these! Get GOD'S Word in your heart in abundance so that HE has something within YOU to work with! Amen! Now fully expect His manifested presence to meet the needs of the people that YOU pray for, preach to, or lay hands on for healing!
